| 摘 要： | 子域Ritz法是基于最小势能原理，通过能量变分极值方法，寻求弹性系平衡问题的最佳逼近值，合理地在特定子域选择附加基函数，在很多情况下能够得到优于Ritz法的解答。它在位移基函数的选择上较Ritz法更为灵活。

| Abstract: | The sub field Ritz method presented in this paper is based on the minimum potential energy principle to search an optimum approximate solution of elastic system balance problem through the method of energy variation extreme value. If additional primary function is selected reasonably, better solutions than the ones gotten by Ritz method can be attained. Its displacement primary function can be selected more flexibly than Ritz method. |
