【摘要】 <正>The purpose of this paper is to demonstrate a shape preserving topology optimization design approach suppressing the warping deformation of local structural domains.As structural deformation consists of rigid body motion and warping deformation,we propose using the elastic strain energy of the local domain to measure the warping deformation.Constraint on the更多还原
