| 摘 要： | 研究了复合材料层合开顶扁球壳的非线性动态屈曲问题。建立了对称层合圆柱正交异性开顶扁球壳考虑横向剪切的非线性振动微分方程，根据突变理论建立了该壳体动态屈曲的突变模型，得到了动态屈曲的临界方程。

| Abstract: | The problem of nonlinear dynamic buckling of symmetrically laminated, cylindrically orthotropic truncated shells including transverse shear has been studied. The differential equations of nonlinear vibration of the shell are obtained. The cusp catastrophe model of nonlinear dynamic buckling is developed by using catastrophe theory. The dynamic buckling conditions are discussed and the critical equation of dynamic buckling of the shell is obtained. |
