摘要
本文对大挠度刚塑性柱壳在轴对称冲击侧压作用下的塑性动力响应进行了讨论。文中引入了几何非线性和轴向膜力的影响,给出了不同广义屈服面情况下的解。
The large deformation effect is an important factor in the dynamic plastic response of serveral practical problems,especially,for the flexible thin-wall structures subjected to transverse dynamic loads.In this pa- per,the dynamic response of rigid-plastic cylinderical shells subjected to axisymmetric impulsire loading is considered.The governing equation of the dynamic problem is of nonlinear type,different yield conditions which are the approximation Trasca yield surfaces are employed.Analytical formulas and numerical results for the different phases of motion are given.
