The tapered composite laminates are optimized by a patchwise layup design method. In this approach, the weight of tapered composite laminates under the strength constraints was minimized. For this purpose, stacking sequences and the number of plies were optimized. The design variables were the discrete ply angles such as 0 o , +/-45 o , and 90 o and the number of plies in each...
A patchwise optimal layup design method is developed for the tapered composite laminates in this paper. In the patchwise layup design method, the optimal solution is obtained by integration of an expert system shell, genetic algorithm (GA) and finite element method. In this approach, the weight of composite laminates with ply drop under strength constraint is minimized and for this purpose, stacking...
