Topology optimization for pressure loading using the boundary element-based moving morphable void approach
This paper presents an approach for the topology optimization problem with pressure load. The approach is constructed by combining Moving Morphable Void (MMV) approach with Boundary Element Method (BEM). In this approach, the pressure boundary is explicitly described using B-spline curves and optimized simultaneously with free boundary. In the current approach, not only the moving load boundary is traced without any predefined identification scheme, but also the pressure load can be applied accurately to the structure without any needs for special load interpolation scheme. Several numerical examples in two dimensions are explored to demonstrate the effectiveness and advantages of the present approach.
