【摘要】 本文提出了一种摄动加权残量法或称 PWRM。这对我们去解决薄板几何非线性问题提供了一种有效的方法。PWRM 可以克服摄动法用于其他边界形状薄板几何非线性问题所遇到的困难,也可以避免加权残量法须求解非线性代数方程组的缺点,明显地减少了计算工作量。更多还原

【Abstract】 In this paper,a method of "perturbation-Weighted Residual" or PWRMY is discussed.It is a useful method for us to solve geometrically nonlinear problems of the thin plate.The difficults for perturbation method to solve geometrically nonlinear problems of the thin plate with other boundary forms may be overcome by PWRM,and the fault for Weighted Residual Method to solve nonlinear algebr- aical equations may be avoided.It is obvious that workload can be reduced.更多还原
