- 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.
