Topology optimization utilizing inverse motion based form finding

摘要: Topology optimization at finite strain setting using the concept of inverse motion based form finding is introduced. This novel procedure allows boundary conditions and shape structure in operating, deformed, state to be prescribed. The outcome algorithm will undeformed structure, i.e. which should manufactured. objective considered find stiffest for a given amount material. problem regularized Helmholtz filter formulated deformed configuration. Both elastic value partial differential equation associated with are solved element method. sequence convex separable approximations. paper closed by 2D as well 3D numerical examples that clearly illustrates method able optimal solutions topology problems.
