This contribution gives an insight into the field of structural optimization and its application for two detail engineering examples by means of the commercial software TOSCA [1]. Figure 1: Shrink-fit Design in Partial View. Structural Optimization In the detailed engineering work, some component designs must be improved and optimized. This demands the availability of optimization software, which can handle linear and non-linear problems. We use TOSCA with interfaces to the non-linear FEM solver ABAQUS [2] and the durability tool FEMFAT [3]. Based on these tools, topology and shape optimization of complex 2D and 3D ABAQUS models with an arbitrary number of load cases and boundary conditions can be performed. Topology optimization is used to find a structure Figure 2: Initial and Optimized Hub Bore Contour within a given design space.
