In this paper a simulation based optimization procedure, based on the combination of the Simulated Annealing and the Nelder Mead algorithms, for the time reduction of the thermal cure cycle of composite laminates, has been proposed and discussed. The cycle time has been assumed as the objective function to be minimized, taking into account technological limitations by the means of a penalty function. Several simulations have been performed to test the proposed method and investigate the influence of the optimization algorithm parameters on the quality of the solution and the convergence rate of the algorithm, evidencing the capability of the procedure to converge to an optimal process window for cure cycle design

Abstract
In this paper a simulation based optimization procedure, based on the combination of the Simulated Annealing and the Nelder Mead algorithms, for the time reduction of the thermal cure cycle of composite laminates, has been proposed and discussed. The cycle time has been assumed as the objective function to be minimized, taking into account technological limitations by the means of a penalty function. Several simulations have been performed to test the proposed method and investigate the influence of the optimization algorithm parameters on the quality of the solution and the convergence rate of the algorithm, evidencing the capability of the procedure to converge to an optimal process window for cure cycle designI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
