摘要
应用无网格局部Petrov-Galerkin法对船舶平直板结构进行了研究.运用最小二乘法和加权余量法来求解结构位移场量的逼近函数,给出了问题的控制方程和刚度方程.通过算例与有限元法计算结果进行了比较分析,验证了文章提出方法的正确性.文章研究对于分析船舶结构变形和应力具有良好的适用性.
The paper employed the meshless local Petrov-Galerkin method to assess the ship structures stress analysis. The displacement field approximation function is obtained by employing Moving-least Square method,and the governing equation and the stiffness matrix of the structural are established. Numerical examples show the solutions are good agreement between FEM-ANSYS and the proposed approach, which verifies the validity of the presented method for stress analysis of the ship structural.
