Abstract

The well-known SIMP method has been completed for suppressing the checkerboard pattern and other corner contact configuration appearances. The extended and corner contact optimality is used for interpreting some quasi-2D optimal topologies. The calculation results of presented algorithms are in close similarity to the known exact analytical solutions. Comparing the sub-meshing of the presented methods, CO-SIMP is the most advanced one, because there are minimum four times more design variables at the same number of FEs. The corner-contact penalty function was developed for 3D topologies as well.
