Sammanfattning

The topology optimization problem is formulated in a phase-field approach. The solution
procedure is based on the Allan-Cahn diffusion model. The functional defining the minimization problem
includes a gradient term which introduces cost for boundaries and thereby regularizing the problem. To
avoid non-physical densities obstacles are introduces. It is shown that the problem can be stated as a
variational inequality or a max-min problem. The numerical solution procedure are based on the finite
element method and Howard’s algorithm.
