摘要
应用边界元法对带缺口和圆孔的单向受拉板进行弹塑性分析,给出了圆孔与缺口之间各点的应力以及屈服区域随载荷的演变情形。分析了当缺口从椭圆形逐渐变为尖角形时的屈服区情况。同时给出含微小双椭圆孔受拉板两孔间的应力及屈服区的情况。
This paper studies the notched tensile specimen with a circle hole for the analysis the elastic—plastic behavious.The stresses and plastic region change have been exhibited.Meanwhile the tensileplate with two small ellipse holes was studied.The results obtained in this paper will be very usefuland voluable fo the study of mechanism of elastis—plastic fracture and practical design in engineer-ing.
