Reliability-based topology optimization for freely vibrating continuum structures with unknown-but-bounded uncertainties

This study investigates a novel reliability-based topology optimization framework to determine optimal material configurations for freely vibrating continuum structures with unknown-but-bounded uncertainties. Firstly, the optimization formulation for freely vibrating continuum structures with fundamental eigenfrequency and eigenfrequency gap constraints is described. Uncertainty quantification analysis is conducted to determine the feasible...
