摘要
该文根据虚功原理,采用罚函数法满足本征边界条件,得到了功能梯度材料板弯曲的无网格法控制方程,并给出了两个数值算例.算例表明该方法具有节点少、精度高等优点.
Based on the principle of virtual work, the governing equation for bending of functionally graded rectangular plates is derived by using the meshless method. The penalty method is used to deal with displacement boundary conditions. Two numerical examples are presented showing that the meshless method has some merits： it uses a small number of grid points with high precision.
