3D Corbel
3D corbel fixed at the top and bottom and loaded with a distributed force applied at its free end.
A unified approach for topology optimization with local stress constraints considering various failure criteria: von Mises, Drucker–Prager, Tresca, Mohr–Coulomb, Bresler–Pister and Willam–Warnke.
Problem description
The 3D model above corresponds to the stress-constrained topology optimization results for the 3D corbel shown below. The optimization results were obtained using 250k regular hexahedral elements on a MATLAB implementation of an augmented Lagrangian-based formulation for topology optimization with local stress constraints. The stress constraints are based on a unified failure function that is able to represent several failure criteria such as von Mises, Drucker–Prager, Tresca, Mohr–Coulomb, Bresler–Pister, and Willam–Warnke.
