摘要
编制了 3～ 8节点平面应力弹塑性有限元程序 ,对中心有圆孔的薄板类零件受拉力作用时板内塑性区的扩展过程进行了模拟 ,结果同试验值一致。本程序对于探寻金属零件的塑性失效过程 ,控制塑性变形有实际意义。
In this paper,3～8 nodes plane stress elastoplastic model is presented The plastic area of thin plate with hole in its central suffered from distributed load in its plate is simulated, the result is in good accordance with the experiment It is important to guide machine design and to control the plastic failure
