Abstract
A weak point of the density based approach to topology optimization has been its disability to handle design dependent surface loads like pressure loads without introducing special parameterizations of the load surfaces. In this paper we suggest a way to resolve the problem. Based on a mixed pressure-displacement finite element model we impose the pressure load through an incompressible hydrostatic fluid. One continuous design variable pr. element interpolates between solid elastic material and incompressible fluid. The method is straightforward to implement and applies to two as well as three dimensions.
