摘要
在介绍薄板大挠度问题的控制方程及其推导过程的基础上,根据渐近迭代方法,分别用DRM方法和MFS方法近似特解和齐次解,得到求解薄板大挠度弯曲问题的DRM-MFS无网格近似方法,再通过数值算例验证方法的有效性及准确性.
Undering introducing the derivation of control equation on large deflection problem of thin plat,applying incremental iteration method,and solving the approximate particular solution and homogeneous solution by DRM and MFS respectivly,a DRM-MFS meshless algorithm was presented for the large deflection problem of thin plate.The effectiveness and accuracy of this method were verified through numerical examples.
