Topology optimization of continuum structures with local stress constraints
Pierre Duysinx,Martin P. Bendsøe +1 more
TL;DR: In this paper, the authors introduce an extension of current technologies for topology optimization of continuum structures which allows for treating local stress criteria for porous composite materials, initially by studying the stress states of the so-called rank 2 layered materials, then, on the basis of the theoretical study of the rank 2 microstructures, they propose an empirical model that extends the power penalized stiffness model (also called SIMP for Solid Isotropic Microstructure with Penalization for intermediate densities).
