A method for the multi-scale design of composite thermoelastic macrostructure and periodic microstructure with multi-phase materials is proposed. A concurrent topology optimization model of macrostructure and microstructure is established, where the objective is to maximize the macrostructural stiffness subject to volume constraints on the macro-material distribution and phase materials. Based on...
In this paper, a method for the concurrent topology optimization of macrostructural material distribution and periodic microstructure under dynamic loading based on the equivalent static loads (ESLs) in the time domain is proposed. The sensitivity analysis of the maximal dynamic strain energy with respect to design variables in two scales, i.e., macro and micro scales, is presented. The corresponding...
