Abstract
In the present paper the combinatorial optimization problems dealing with laminate stacking sequence optimization are formulated and studied. Two types of design variables are introduced: 1) classical, discrete and 2) new, continuous ones. In order to obtain the optimal solution a classical genetic algorithm is applied. We are looking for the maximal buckling loads for 2-D multilayered structures subjected to bimodality constraints and FPF constraints. Two special buckling problems are analyzed in details, i.e. buckling of compressed rectangular plates and of cylindrical shells under an external pressure. The results demonstrate the effectiveness and advantages of the use of continuous design variables.
