Abstract
A new methodology for layout optimi zation 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 ob tain 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.
