摘要：The minimum compliance design of thermoelastic structures forced by mechanical and thermal loads simultaneously composed of periodic lattice materials is studied in this paper. The Extended Multi scale Finite Element Method (EMsFEM) is utilized to connect the macro structural and material microstructural scales. In the optimization, sectional areas of the microcomponents are set as design variables under volume constraints. In numerical examples, we discuss the influence of the geometrical dimensions of the material microstructure, the amount of base material and the different ratios of thermal load over the mechanical load on the optimization results.
