A new methodology for layout optimization of structures, which are subjected to transient thermo-mechanical loads, is presented. In the investigation, an evolutionary algorithm of topology optimization is used. For the purpose of the thermomechanical analysis, a new method of cumulative damage summation of the full thermo-mechanical time load history is considered. Moreover, to obtain an easy-to-manufacture shape, a new procedure for the layering reduction of unnecessary material is proposed. The proposed methodology is illustrated in the example of design optimization of a power block device. In the optimization process, the constraints of the maximum total stress in the whole cycle are assumed. As the basis of transient load regime, the TRD 301 regulations are used.
