摘要：Residual stresses are self equilibrating stresses that a portion of the strength of the specimen is used to oppose these stresses. Classical Laminate Plate Theory (CLPT) can be used for calculating of these stresses. In this paper, genetic algorithm is introduced to optimization of stacking sequence. We treat with this problem as Traveling Salesman Problem (TSP). Genetic algorithm (GA) approaches are successfully implemented to the TSP. The residual stresses of a constant thickness composite plate, which is obtained by the analytical method, was used as the fitness function in the GA to find its minimum value by arrange the ply stacking sequence. Two examples of constant thickness and symmetrical composite laminate plates were used to examine the performance of the proposed algorithms. The results of computational tests presented are very encouraging
