Topology Optimization of Elastoplastic Behavior Conditions by Selectively Suppressing Plastic Work
This work conducted topology optimization with an implicit analysis of elastoplastic constitutive equation in order to design supporting structures for unexpected heavy loading conditions. In this topology optimization model, plastic work was extracted from strain energy and selectively employed in the objective function according to deformation mode. While strain energy was minimized in elastic deformation areas, in elastoplastic deformation areas, the plastic work was minimized for thedoi:10.3390/math8112062 fatcat:vqlylbdztjaxzl2p4nwhqux3om
