Abstract (EN): This paper aims to obtain the optimal design of laminated composite structures. The design variables are specified as the ply angles and the laminate thicknesses. The objective is to obtain a structure with minimum weight that is capable of carrying a given set of static external forces without failure. The solution strategy consists of addressing the problem sequentially at two levels, each having a different algorithm and a separate set of design variables. The optimization techniques use a combination of sensitivity analysis combined with optimality criteria and mathematical programming. The adequacy of the solution is assured by constraints limiting stresses and displacements.
