Recent advances in the mathematical formulations for structural design optimization using thermoelasticity concepts play pivotal role in the development of science and technology especially aerospace engineering. As thermoelasticity is a branch of science that deals with the analysis of stresses caused by thermally induced strains which are in the elastic (recoverable) range, but the material interfaces also plays a pivotal role in the actual performance of a structure, often dictating lifetime and failure characteristics, tolerances and processing choices.The motivation of the present study...
