Abstract

A new method for the structural shape optimization is proposed in this paper by a combination of the finite and boundary elements, which makes use of the boundary element mesh for the region under successive geometrical change and the finite element mesh for the remaining region. Using the coupled formulation and computation, i) remeshing on the boundary is easier, ii) the system equation has smaller fully-populated submatrices and iii) the finite element subregion and its stiffness matrix is invariant during iteration computation. The method is applied with satisfactory efficiency to the optimized local shape determination.
