Abstract:

The paper is devoted to the optimization in two-scale thermoelastic problems. The problems are solved by means of evolutionary computation and direct analysis based on a numerical homogenization. Direct thermoelastic analysis with representative volume element (RVE) and finite element method (FEM) is performed. Design variables in optimization tasks describe micro-structure, whereas optimization functionals are formulated on the basis of the quantities derived from a macro scale. Numerical examples of the optimization are included.
