WebA common method of modeling damping is Rayleigh damping, where two damping coefficients are specified. This type of damping is not directly related to any physical process, but must be seen as a way to take the total damping of a structure into account. Rayleigh damping introduces damping in a form based on Equation 2-20. 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.
