On the inclusion of plastic material behavior within the thermodynamic topology optimization

Abstract: Accounting for the real material behavior in topology optimization is essential since it determines the final optimal structure. For considering a plastic material behavior, we propose a surrogate plasticity model within the thermodynamic topology optimization to handle this complex material behavior in a resource‐efficient manner. We model physically correct plastic strains analogously to classic plasticity models but without path‐dependence and hysteresis during the course of optimization. This is verified by comparison to classic elasto‐plastic models. To demonstrate the necessity of accounting for the realistic material model, we present optimization results where the structural changes due to plastic deformations become apparent.
