Detailed Description

This class describes the magnetostriction operator of the landau lifshcitz system EMM_LandauLifschitzSystem.

The magnetostriction magnetic excitation $ H_m(M) $ at the l-coordinate $l \in [0,3[$ is modelized as follow

$\displaystyle H_m(M)_l = \displaystyle \bar H \sum_{kij \in [0,3[^3} \lambda^m_{lkij} \varsigma_{ij} M_k$

We assume a linear dependence of the stress tensor $\varsigma = { \varsigma_{ij} }$ (expressed in Pa) with respect of the elastic strain tensor $\displaystyle \epsilon^e = { \epsilon^e_{st}}$ by the inverse form of Hook’s linear law : $\displaystyle \varsigma_{ij}= \sum_{st \in [0,3[^2} \lambda^e_{ijst} \epsilon^e_{st} = \lambda^e : \epsilon^e$ when :

$\epsilon^e_{st}= \epsilon_{st}(U)-\epsilon_{st}^m(M)$ with

$\lambda^e$ is the elastic tensor expressed in Pa.
$\epsilon_{st}(U)=\displaystyle \frac{1}{2} \left ( \frac{\partial U_s}{\partial X_t}+ \frac{\partial U_t}{\partial X_s} \right )$ which is the displacement tensor and
$\epsilon_{st}^m(M)= \displaystyle \sum_{pq \in [0,3[^2} \lambda^m_{stpq}\cdot M_p \cdot M_q$ with is a magnetic strain tensor.
$\epsilon(U)$ , $\epsilon^e$ and $\epsilon^m(M)$ are non-dimensional.

The stress tensor $\varsigma$ and displacement $ U $ satisfies the conservation of momentum equation with respect to time $\tau$ :

$\rho \displaystyle \frac{\partial^2 U}{\partial \tau ^2} - Div(\varsigma)=0$ which is modelized by the EMM_DisplacementOperator with $Div(.)=\frac{\partial \cdot}{\partial X} = div(.) \frac{1}{L}$ where $(div(.)=\frac{\partial . }{ \partial x}$ and $ X=L.x $

We suppose the limit condition $ u=U^0 $ on $\partial \Omega_0$ and $\varsigma.n = C$ on $\partial \Omega_1$ where n is the normal of the boundary.

By denoting:

$\rho$ the mass density expressed in $kg.m^{-3}$
$M \otimes M$ is a symmetric matrix of size 3x3 $[M \otimes M]_{ij}=M_i . M_j \in R^3 \times R^3$
U : V is a 2-tensor product of 2 matrices, U of size 3x3, V of size 3x3, $\displaystyle [U : V ] = \sum_{ij} U_{ij} . V_{ij} \in R$
A : U is a 4-tensor product of a symmetric 4-tensor of size 3x3x3x3, U a matrix of size 3x3 $\displaystyle [ A : U ]_{ij} = \sum_{kl} A_{ijkl}. U_{kl} \in R^3 \times R^3$
The tensors $\lambda^m$ and $\lambda^e$ are symmetric : $\lambda_{ijkl} =\lambda_{jikl} = \lambda_{klij} = \lambda_{ijlk}$ and positive definite $\displaystyle \sum_{ijkl} \lambda_{ijkl} \xi_{ij} \xi_{kl} \geq \lambda \sum_{ij} \xi_{ij}^2$

we obtain:

$\displaystyle H_m(M)= \bar H \left [ \lambda^m : \left \{ \lambda^e:\epsilon(U) - \lambda^e:\left ( \lambda^m: M \otimes M \right ) \right \} \right ]. M$ when U verifies the conservation of momentum equation:

$\displaystyle \rho \frac{\partial^2 U}{\partial \tau^2} - Div( \lambda^e:\epsilon(U))= - Div(\lambda^e:\lambda^m : M \otimes M )$

We normalize the variables by $ U=Lu $ , $M=M_s \sigma(x) m$ , $ H_m(M)=M_s h_m(m) $ , $\tau = \displaystyle \frac{-1}{\gamma \mu_0 M_s} t$ , $\rho=\bar \rho \kappa$ and $Div(.)=\frac{1}{L} div(.)$ where L is the reference length, $ M_s $ is the reference magnetization at saturation and $M_{s_i}$ is the magnetization at saturation of the point where m is computed, $C= \bar \lambda^e c$ , and $ u^0=U^0/L $ .

u verifies the equation :

$\displaystyle \kappa \frac{\partial^2 u}{\partial t^2} - div( \tilde \lambda^e:\epsilon(u))=-div(\sigma^2(x) \tilde \lambda^e:(\tilde \lambda^m:m \otimes m) )$ where $\displaystyle u_{|\partial \omega_0}= u^0$ and $\displaystyle \left ( \tilde \varsigma . n \right)_{|\partial \omega_1}= c$ .

and

$\displaystyle h_m(m)= M_s H(M)= \bar H \cdot . \frac{L_e}{M_s^2} \cdot \left [ \tilde \lambda^m : \left \{ \tilde \lambda^e:\epsilon(u) - \sigma(x)^2 \tilde \lambda^e:\left ( \tilde \lambda^m: m \otimes m \right ) \right \} \right ]. \sigma(x) m$ .

with

$\displaystyle \tilde \lambda^e=\lambda^e \frac{1}{L_e}$ , will be defined later.
$\tilde \lambda^m=\displaystyle \lambda^m M_s^2$ ,
$\kappa = \displaystyle \rho \frac{L^2}{L_e.t_m^2}$ with $t_m=\frac{-1}{\gamma \mu_0 M_s}$
$\sigma(x)=\displaystyle \frac{M_{s_i}}{M_s}$
$c =\displaystyle C \frac{1}{L_e}$ , the surface tension.

To compute the adimensionized energy defined by $\nabla_m E . \delta = -2 \sigma h(m) . \delta$ , we decompose $h_m= \bar H \cdot . \frac{L_e}{M_s^2} \left ( h_m^e-h_m^m \right )$ with :

$h_m^e(m)=\displaystyle \sigma \left ( \tilde \lambda^m:\left ( \tilde \lambda^e : \varepsilon(u) \right ) \right ) \cdot m$
$h_m^m(m)=\displaystyle \sigma^3 \left ( \tilde \lambda^m:\left ( \tilde \lambda^e : \left ( \tilde \lambda^m : m \otimes m \right ) \right ) \right ) \cdot m$

To compute the energy corresponding to the term $ h_m^m(m) $ of $ h_m(m) $ , we can prove that, if we denote by $Q(m)=\displaystyle \left ( \tilde \lambda^e : \left ( \tilde \lambda^m : m \otimes m \right ) \right ) :\left( \tilde \lambda^m : m \otimes m \right )$ , we have :

$\nabla_m Q (m). \delta = \displaystyle 4. \left [ \left ( \tilde \lambda^m:\left ( \tilde \lambda^e : \left ( \tilde \lambda^m : m \otimes m \right ) \right ) \right ) \cdot m \right ] \cdot \delta$

So $h_m^m(m). \delta = - \displaystyle \frac{1}{4} \sigma^3 \nabla Q(m). \delta$ .

By definition $\nabla_m E^m(m) . \delta = -2 . \sigma h_m^m(m) . \delta$ , so $E^m(m) = \displaystyle \frac{1}{2} \sigma^4 Q(m)$

To compute the energy corresponding $ E^e(m) $ to the term $ h_m^e(m) $ of $ h_m(m) $ , coupled with the displacement adimensionized equation of u : $\displaystyle \kappa \frac{\partial^2 u}{\partial t^2} - div( \tilde \lambda^e:\epsilon(u))=-div(\sigma^2(x) \tilde \lambda^e:(\tilde \lambda^m:m \otimes m) )$ gives :

$h_m^e(m) . \delta= \displaystyle \sigma \left ( \tilde \lambda^e:\varepsilon(u) \right ) : \left ( \tilde \lambda^m: m \otimes \delta \right )$
by using $\delta_{|_{\partial \omega_0}}=0$ , (no velocity on dirichlet boundary) and $\displaystyle \left ( \tilde \lambda^e:\left (\epsilon(u)-(\tilde \lambda^m:m \otimes m)\right) \right) \cdot n = c$ on $\partial \omega_1$ and by green formula, using the symmetry of tensors, we have: $\displaystyle \int_\omega div\left (\tilde \lambda^e:\varepsilon(u)\right ) . \delta d\omega - \int_\omega div\left (\sigma^2 (x) \tilde \lambda^e:\left(\tilde \lambda^m:m \otimes m \right)\right) \cdot \delta dx =$

$\int_{\partial \omega_1} c.\delta d\sigma - \int_\omega \left(\tilde \lambda^e:\varepsilon(u) \right) : \varepsilon(\delta) d\omega + \int_\omega \sigma^2 \left(\tilde \lambda^e: \left ( \tilde \lambda^m: m \otimes m \right ) \right) : \varepsilon(\delta) dx$

By multipliing the displacement adimensionised equation by $\delta=\frac{\partial u }{\partial t}$ over all the domain, we obtain (c is independent from time) :

$\displaystyle \frac{1}{2}. \frac{d}{dt} \int_\omega \kappa \left \| \frac{\partial u }{ \partial t} \right \|^2 d\omega +\int_\omega \left( \tilde \lambda^e:\varepsilon(u) \right):\varepsilon(\frac{\partial u}{\partial t}) d\omega = \displaystyle \int_\omega \sigma^2(x) \left ( \left( \tilde \lambda^e:\left( \tilde \lambda^m:m \otimes m \right) \right):\varepsilon \left (\frac{\partial u}{\partial t} \right ) \right ) dx + \frac{d}{dt} \int_{\partial \omega_1} c. u d\sigma$

Then, we have

$\displaystyle \int_\omega \sigma^2 . \left ( \varepsilon \left (\frac{\partial u}{\partial t} \right ) : \left( \tilde \lambda^e:\left( \tilde \lambda^m:m \otimes m \right) \right) \right ) dx =$ $\displaystyle \frac{1}{2}. \frac{d}{dt} \int_\omega \kappa \left \|\frac{\partial u }{ \partial t} \right \|^2 d\omega +\frac{1}{2} \frac{d}{dt} \int_\omega \left( \tilde \lambda^e:\varepsilon(u) \right):\varepsilon(u) d\omega - \frac{d}{dt} \int_{\partial \omega_1} c.u d\sigma$

But $h_m^e(m) . \sigma \frac{\partial m}{\partial t} = \displaystyle \sigma^2 . \left ( \tilde \lambda^e:\varepsilon(u) \right ) : \left ( \tilde \lambda^m:m \otimes \frac{\partial m }{\partial t } \right ) = \displaystyle \frac{1}{2} \sigma^2 \left ( \tilde \lambda^e:\varepsilon(u) \right ) : \left ( \frac{\partial}{\partial t} \left ( \tilde \lambda^m:m \otimes m \right ) \right )$

So $h_m^e(m).\sigma \frac{\partial m}{\partial t} = \displaystyle \frac{1}{2} \sigma^2 \frac{\partial }{\partial t} \left( \tilde \lambda^e:\left( \tilde \lambda^m:m \otimes m \right):\varepsilon(u) \right) -\frac{1}{2} \sigma^2 \frac{\partial \varepsilon(u)}{\partial t} : \left( \tilde \lambda^e:\left(\tilde \lambda^m:m \otimes m \right)\right)$

So $h_m^e(m).\sigma \frac{\partial m}{\partial t} = \displaystyle \frac{1}{2} \sigma^2 \frac{\partial }{\partial t} \left( \tilde \lambda^e:\left( \tilde \lambda^m:m \otimes m \right):\varepsilon(u) \right)$ $- \frac{1}{4}. \frac{d}{dt} \int_\omega \kappa \|\frac{\partial u }{ \partial t}\|^2 d\omega - \frac{1}{4} \frac{d}{dt} \int_\omega \left( \tilde \lambda^e:\varepsilon(u) \right):\varepsilon(u) d\omega + \frac{1}{2} \frac{d}{dt} c.u d\sigma$ .

So we using the definition of energy $\displaystyle \frac{dE^e}{dt}=-2.\sigma h_m(m).\frac{\partial m}{\partial t}$ ,

$\displaystyle \frac{dE^e}{dt} = \frac{1}{2}. \frac{d}{dt} \int_\omega \kappa \|\frac{\partial u }{ \partial t}\|^2 d\omega + \frac{1}{2} \frac{d}{dt} \int_\omega \left( \tilde \lambda^e:\varepsilon(u) \right):\varepsilon(u) d\omega - \frac{d}{dt} \left ( \int_\omega \sigma^2 . \left( \tilde \lambda^e:\left( \tilde \lambda^m:m \otimes m \right ) \right) : \varepsilon(u) d\omega \right ) - \frac{d}{dt} \int_{\partial \omega_1} c. u d\sigma$ .

we can conclude that

$E^e(m)= \frac{1}{2}. \int_\omega \kappa \|\frac{\partial u }{ \partial t}\|^2 d\omega$ $+ \frac{1}{2} \int_\omega \left( \tilde \lambda^e:\varepsilon(u) \right):\varepsilon(u) d\omega$ $- \int_\omega \sigma^2 \left( \tilde \lambda^e:\left( \tilde \lambda^m:m \otimes m \right ) \right) : \varepsilon(u) d\omega$ $- \int_{\partial \omega_1} c. u d\sigma$

The magnetostriction energy is $E(m,u)= \bar H \cdot . \frac{L_e}{M_s^2} (E^e(m,u)+E^m(m))$ :

$E(m,u)=\displaystyle \bar H \cdot . \frac{L_e}{M_s^2} \dot [$

$\displaystyle \frac{1}{2} \int_\omega \sigma^4(x)[\tilde \lambda^e:(\tilde \lambda^m:m \otimes m)]:(\tilde \lambda^m:m \otimes m) d\omega$

$\displaystyle -\int_\omega \sigma^2(x) \epsilon(u):(\tilde \lambda^e:(\tilde \lambda^m:m \otimes m)) d\omega$

$\displaystyle +\frac{1}{2} \int_\omega (\tilde \lambda^e:\epsilon(u)):\epsilon(u) d\omega$

$\displaystyle +\frac{1}{2} \int_\omega \kappa |\frac{\partial u}{\partial t}|^2d\omega$

$\displaystyle -\int_{\partial \omega_1} c.u d\sigma ]$

On the cell i, the p-coordinate of the magnetostriction magnetic excitation is computed by the formula in the adimensionized non cubic cell $\omega_i$ where $|\omega_i|=h_x.h_y.h_z$ is :

$h_m(m)_p = \displaystyle \bar H \cdot . \frac{L_e}{M_s^2} \sum_{pqkl} \tilde \lambda^m_{pqkl} \left ( \sum_{rs} \tilde \lambda^e_{klrs} \left ( \epsilon_{rs} - \sum_{tv} \tilde \lambda^m_{rstv}.\sigma_i^2 m_t.m_v \right ) \right ) \sigma_i m_q$ .

m is the normalized magnetism at cell i,
is the t-coordinate of m at cell i
$\displaystyle \epsilon_{rs}= \displaystyle \frac{1}{|\omega_i|} \int_{\omega_i} \frac{1}{2} . \left ( \frac{\partial u_r}{\partial x_s}+ \frac{\partial u_s}{\partial x_r} \right )d\omega_i$ when is the r-coordinate of u within the cell i
to compute the displacement u, see the EMM_DisplacementOperator class
to compute $\displaystyle \epsilon_{rs}$ see the method EMM_DisplacementOperator::computeElasticTensor().
to compute see the method EMM_MagnetostrictionOperator::computeMagneticExcitationField().

The gradient of $ h_m$ at m in the direction $\delta$ is, if we suppose the variation of u with respect to m is negligeable (and as it is not, it is not implemented):

$\nabla h_m(M)[\delta]= h_g(u,m,m,\delta) + 2.h_g(u,\delta,m,m)$ where

$h_g(u,m^l,m^m,m)_p = \displaystyle \bar H \cdot . \frac{L_e}{M_s^2} \sum_{pqkl} \tilde \lambda^m_{pqkl} \left ( \sum_{rs} \tilde \lambda^e_{klrs} \left ( \epsilon_{rs} - \sum_{tv} \tilde \lambda^m_{rstv}.\sigma_i^2 m^l_t.m^m_v \right ) \right ) \sigma_i m_q$ .

Now if we use a magnetic normalisation of $\lambda^e = \tilde \lambda^e L_e$ with $L_e= \mu_0 M_s^2$ , we choose $\bar H=\frac{1}{\mu_0}$ so that

$\displaystyle h^{nm}_m(m)= M_s H(M)= \tilde \lambda^m : \left \{ \tilde \lambda^e:\epsilon(u) - \sigma(x)^2 \tilde \lambda^e:\left ( \tilde \lambda^m: m \otimes m \right ) \right \}. \sigma(x) m$ .

and

$E^{mn}(m,u)=$ $\displaystyle \frac{1}{2} \int_\omega \sigma^4(x)[\tilde \lambda^e:(\tilde \lambda^m:m \otimes m)]:(\tilde \lambda^m:m \otimes m) d\omega$ $\displaystyle -\int_\omega \sigma^2(x) \epsilon(u):(\tilde \lambda^e:(\tilde \lambda^m:m \otimes m)) d\omega$ $\displaystyle +\frac{1}{2} \int_\omega (\tilde \lambda^e:\epsilon(u)):\epsilon(u) d\omega$ $\displaystyle +\frac{1}{2} \int_\omega \kappa |\frac{\partial u}{\partial t}|^2d\omega$ $\displaystyle -\int_{\partial \omega_1} c.u d\sigma$

If we use an elastic normalisation of $\lambda^e = \tilde \lambda^e L_e$ with $L_e= \rho_s V_s^2$ , we choose $\bar H=\frac{M_s^2}{\rho_s V_s^2 }$ so that: $\displaystyle h^{en}_m(m)= M_s H(M)= \tilde \lambda^m : \left \{ \tilde \lambda^e:\epsilon(u) - \sigma(x)^2 \tilde \lambda^e:\left ( \tilde \lambda^m: m \otimes m \right ) \right \}. \sigma(x) m$ .

$E^{en}(m,u)=$ $\displaystyle \frac{1}{2} \int_\omega \sigma^4(x)[\tilde \lambda^e:(\tilde \lambda^m:m \otimes m)]:(\tilde \lambda^m:m \otimes m) d\omega$ $\displaystyle -\int_\omega \sigma^2(x) \epsilon(u):(\tilde \lambda^e:(\tilde \lambda^m:m \otimes m)) d\omega$ $\displaystyle +\frac{1}{2} \int_\omega (\tilde \lambda^e:\epsilon(u)):\epsilon(u) d\omega$ $\displaystyle +\frac{1}{2} \int_\omega \kappa |\frac{\partial u}{\partial t}|^2d\omega$ $\displaystyle -\int_{\partial \omega_1} c.u d\sigma$

We have the relation $h^{mn}=h^{en} \cdot \frac{\rho_s V_s^2 }{\mu_0 M_s^2}$ and $E^{mn}=E^{en} \cdot \frac{\rho_s V_s^2 }{\mu_0 M_s^2}$

For example in an hyper-elastic bar of size 4 micron discretized with 32 elements, when

$L=1.25.e^{-7} m = \frac{4.e^{-6}}{32}$ ,
$\gamma=-1.76e^{11} A.s/kg$ ,
$\mu_0=1.257e^{-6} m.kg/ s^{2}.A^{2}$ ,
,
,
$\rho=7870 kg/m^3$
and $\nu=0.3$ which gives $\lambda^e= \lambda+2\mu = E.\frac{1-\nu}{(1+\nu).(1-2\nu)} = 210e^9.\frac{0.7}{1.3*0.4} Pa = 2.82e^{11} Pa$ ,

For the both adimensionments :

$t_m = \frac{-1}{\gamma \mu_0 M_s }= 2.75e^{-12}s$
the time step for the elatic equation $dt=7.57 t_m = L.\sqrt{ \frac{\kappa}{\lambda^e} } . t_m$

We have for the magnetic adimensionment:

$\tilde \lambda^e = 77 840.5349$
$\kappa = 4 465 832.78$

We have for the elastic adimensionment:

$\tilde \lambda^e = 1.0651687$
$\kappa = 61.26$

The factor between the 2 energies depending on the approximation is $\frac{\rho_s V_s^2}{\mu_0 M_s^2}= 72 878.20$
