原始语种摘要: In this work, the non-linear dynamic instability and responses parametric vibration of sandwich composite plates subjected to periodic in-plane compressive load applied along two opposite edges are theoretically analyzed using the extended dynamic stiffness method. The problem is solved for four different sets of boundary conditions. The authors present how to establish the exact dynamic stiffness matrices of rectangular sandwich plates subjected to periodic in-plane forces based on von Karman’s large deflection plate theory. A set of second-order ordinary differential nonlinear equations of extended Mathieu-Hill type with periodic coefficients is formed to determine the regions of parametric instability and non-linear responses based on Bolotin’s method. Therefore, the...
