翘曲变形的模拟中，采用平面膜元和弯曲板元组成的平板型壳元模型，并提出了基于制品表面网格的改进模型，避免了使用传统板壳模型的缺陷。

"How did these beautiful rainbow-tints get into the shell of the fresh-water clam, buried in the mud at the bottom of our dark river?"

"那些彩虹是如何住进这新鲜软壳蛤的壳，而且是在很深的河底的泥里？"

The nonlinear dynamic equations including the initial geometric imperfections of laminated composite cylindrical shells were derived from Hamilton's philosophy. Assuming the transverse displacements to be composed of axially symmetrical part and axially asymmetrical part, the governing equations expressed as displacement forms of dynamic buckling were obtained by Galerkin method. The equations were solved by finite difference method. The effects of impact velocity, lamination angle, initial geometric imperfection on the axial dynamic buckling of laminated composite cylindrical shells were discussed.

由Hamilton原理导出包含初始几何缺陷的复合材料层合圆柱壳的非线性动力方程；将横向位移设为对称及非对称两部分，由Galerkin方法得到以位移形式表达的动力屈曲控制方程，通过有限差分方法求解；讨论了冲击速度、铺层角度、初始几何缺陷等各种因素对复合材料圆柱壳轴向冲击动力屈曲可能产生的影响。
