WebThe Rayleigh-Ritz method is used to develop the analytical model to predict the cured shape of the bistable composite laminate. The coordinated system is shown in Fig. 11.1. The origin sits at the geometric center of the laminate, and the first layer is at the bottom, and the last layer is at the top.
