Topology optimization of exterior acoustic‐structure interaction systems using the coupled FEM‐BEM method

Summary This paper presents an efficient topology optimization procedure for exterior acoustic‐structure interaction problems, in which the coupled systems are formulated by the boundary element method (BEM) and the finite element method (FEM). So far, the topology optimization based on the coupled FEM‐BEM still faces several issues needed to be addressed, especially the efficient design sensitivity analysis for the coupled systems. In this...
