Optimization of thin-walled structures with geometric nonlinearity for maximum critical buckling load using optimality criteria

In this study, two optimality criteria are presented for shape optimization of thin-walled structures with geometric nonlinearity modeled by finite elements. The optimization problem considers the thickness and geometry design variables, and aims to maximize the critical load of the structure subjec...
