摘要
本文求解了矩形长板镦粗时 (出现鼓肚 )的应力场。理论解析解表明 :水平应力 σx 等值曲线呈椭圆形 ;镦粗体内存在呈椭圆曲线界定的拉应力区。探讨了拉应力区与摩擦因子及镦粗体几何参数的关系。
In this paper,the stress field in a long rectangle platen being upset (after the drum profile emerging )is resolved It shows by the theoretical analytic solution that the equivalent lines of the horizontal stress σ x are elliptic curves in shape,and there exists a elliptic tension stress zone in the upsetting body The relation between tension stress zone and the basic parameters including friction factor and geometric dimension of the upsetting body is further studied
