| 摘 要： | 本文讨论并运用边界元法,计算了具有双线性应力应变关系的平面弹塑性问题,计算中将固有应变法运用于边界元的求解中,避开了迭代运算与矩阵更新,并对边界应力的求解方法作了适当的改进。编制了计算机程序,在微机上实现了例题考证及实物计算,得到了较好的结果。

| Abstract: | In this paper, the BEM is discussed and utilized to calculate-the plane elastic-plastic problem which concerns with double-linear stress-strain relation. In computation, inherent strain method is applied to solution of BEM and iterative calculation and matrix renewing are avoided. Moreover, there are some improvements on the solution method of bounderry stress. Computer program has been compiled, and through calculating textual and real examples with microcomputer, the results to be found satisfactory. |
