摘要
本文用数学解析法求解了矩形长板镦粗时 (出现鼓肚 )的应力场 ,定量计算出镦粗体内存在呈椭圆曲线的拉应力区 。
In this paper,the stress field in a long rectangle platen being upset(after bulge profile emerging)is resolved by mathmatic analytic method,the tension stress zones formed elliptic shape curves in upset are found through quantitative calculation,the relation between the zones and the basic upsetting parameters is obtained.
