| 简要论述承受轴向冲击载荷圆柱壳非弹性动屈曲响应的研究进展。采用Ｋａｒｍａｎ－Ｄｏｎｎｅｌｌ运动方程研究轴向流固冲击载荷作用下的圆柱壳轴对称弹塑性动屈曲问题。本构关系采用增量理论，借助增量数值方法求解动力方程组。研究不同边界条件对屈曲的影响，以及径向外压力在不同边界条件下对屈曲的影响。 |
| 英文摘要: |
| The development of research of inelastic dynamic buckling of cylindrical shells under axial impact is reviewed simply. The Karman-Donnell kinetic equation is used to study the problem of the axiasymmetric ekasto-plastic dynamic buckling of cylildrical shells under fluid-Solid impact. The constitution of material utilizes the increment theory and the increment numerical method is used to solve the kinetic equations. The effect of boundary conditions and radial pressure on the dynamic buckling of cylindrical shells is investigated. |
