The ε‐Relaxed Approach in Topology Optimization for Various ε Functions

The inspiration of this contribution was a paper written by Cheng and Guo ]1[ where the E‐relaxed approach for structural topology optimization was applied and a second one paper by Duysinx and Bendsoe ]2[ where continuum structure with stress constraints was considered. In this contribution various ε functions are proposed and discussed for continuum structure from the convergence point of view. The problem is illustrated by FEM examples.
