Short summary
This paper presents an optimization approach to improving the performance of lattice structures subjected to thermal and mechanical loads. The proposed method is demonstrated through examples of battery packs, L-brackets, and machine tool headstocks. The results of numerical verification show that the proposed method enhances the performance of designed structures greatly compared with traditional solid-design and temperature constraints.
