| 摘 要： | 给出了一种半解析方法求解加筋板在横向低速冲击载荷下的非线性弹塑动力响应分析。考虑大变形的影响，采用增量型本构关系，得到膜力、弯矩增量与应变增量的关系，忽略面内惯性力的影响，运用Hamilton变分原理，得到加筋板增量形式动响应控制方程，最后采用增量形式的迦辽金法来求解。

| Abstract: | The elasto-plastic dynamic responses of stiffened plates under lateral low velocity impact load are acquired with a semi-analytical method. By the incremental relations between stresses and strains, the nonlinear dynamic equation expressed by the increments are derived from Hamilton Variational Principle, and Galerkin Method is used to get the discreted dynamic equations and Runge-Kutta Method is adopted to solve. |
