Abstract

Optimization of thermal compliance and linear elastostatic compliance is a common research task that can increase heat dissipation and structural stiffness. In particular, support structures in additive manufacturing (Kuo et al. in Struct. Multidiscip. Optim. 57:183–195, Jan. 2018) or the optimization of heat sinks (Zhou et al. in Struct. Multidiscip. Optim. 54:1045–1060, Oct. 2016) often require the consideration of both objectives. This article deals with the multi-objective topology optimization of frame structures using the weighted sum method for 2D and 3D wireframe meshes. Therefore, an element stiffness matrix is used, which couples both contributions. This automatically leads to holistic design proposals in terms of considering both objectives.
