New research quantifies geometric nonlinearity in material optimization

By PulseAugur Editorial · [1 sources] ·

A new research paper explores the impact of geometric nonlinearity and temperature-dependent material properties on the design of multi-material thermo-mechanical topology optimization. The study introduces a framework that incorporates a finite-strain constitutive model and accounts for temperature variations in titanium, copper, and steel. Results indicate that the constitutive law is the most critical factor, with designs optimized using full physics exhibiting superior performance and temperature robustness compared to those using simplified linear models.

    On the Importance of Geometric Nonlinearity and Temperature-Dependent Properties in Multi-Material Thermo-Mechanical Topology Optimization

    arXiv:2608.10344v1 Announce Type: cross Abstract: Thermo-mechanical compliant devices are commonly designed with small-strain linear elasticity and temperature-independent material properties, even though they might operate hundreds of kelvin above ambient where both assumptions …
