Topology optimization of 3D structures with design-dependent loads

Topology optimization of continuum structures with design-dependent loads has long been a challenge.In this paper,the topology optimization of 3D structures subjected to design-dependent loads is investigated.A boundary search scheme is proposed for 3D problems,by means of which the load surface can be identified effectively and efficiently,and the difficulties arising in other approaches can be overcome.The load surfaces are made up of the boundaries of finite elements and the loads can be directly applied...
