The main purpose of this thesis is to propose a method for structural
optimization which combines the accuracy of featuring an exact, meshed description of shapes
at each stage of the process with the versatility of the level set method
for tracking their evolution. This notably brings into play the device of numerical schemes
for the level set method on simplicial meshes, and the construction of a three-dimensional
local remeshing algorithm.
Independently, we also study two problems related to modeling in structural optimization.
