A multi-material topology optimization with temperature-dependent thermoelastic properties

This is a study on the development of novel multi-material topology optimization scheme considering temperature-dependent thermoelastic properties for engineering structure design. Two cases, three-point-bending beam under uniform temperature field and cantilever non-uniform field, are investigated effects optimization. The proposed compared with two existing approaches: conventional results show that elastic modulus dominantly influences design outcomes, in terms material distribution, structural shape compliance, while thermal expansion coefficient has much more crucial impact determining distribution geometry than compliance. Taken together, findings demonstrate developed can be used to thermally sensitive multi-materials industrial applications, e.g. aerospace structures high polymers additive manufacturing.
