Abstract In this paper, the dynamic snap-through phenomenon of a six-layer asymmetric cross-ply bistable
composite laminated plate (0/0/0/90/90/90) are studied and nonlinear vibrations before, after and during the
dynamic snap-through are demonstrated. The boundary conditions are fixed at the center and free at the four sides.
Considering the von Kármán's large deflection theory, the dynamic and governing equations of the six-layer
asymmetric cross-ply bistable composite laminated plate are established by using the Reddy's third-order shear
deformation theory and the Hamilton's principle. Taking the base excitation amplitude as the control parameter,
