The behaviour of many components subjected to combined thermal and mechanical fatigue loads has great importance in mechanical industry, in particular in the field of vehicles. The damage cumulated by the components as a result of this type of load is estimated through some damage models and their validation is carried out by accelerated fatigue tests that produce the same cumulative damage that would occur in their lifetime in order to reduce time and cost. In this thesis project a calculation tool, by the means of the software AVL CONCERTO, was created for the optimization of the analysis of engine maps measured on the test bench and mission time history profile data recorded in field and the implementation of the damage models just mentioned.
