摘　　要：　研究复合材料叠层板的非线性动力稳定性,分析中考虑大挠度和初始几何缺陷的存在。Catastrophe theory was applied to the investigation of nonlinear dynamic stability of composite laminated plates. The influence of large deflection, initial imperfection, support conditions and ply-angle of the fibers were considered. The catastrophic models and the critical conditions of dynamic buckling of composite laminated plates are obtained.
