The Computation of the Elastic and Plastic Limit Loading Thin-Welled Steel Tube in the Steel Mould

研究在轴向压力、内压力、挤压力和摩擦力作用下钢模内薄壁钢管弹、塑性变形和内力,计算钢管弹、塑性极限载荷,并讨论钢管和钢模间摩擦系数对极限载荷的影响。最后给出算例。

Studies the internal stress and deformation of the thin-welled steel tube in the steel mould under the action of axial force, extrusion stress, internal pressure and frictional force. The elastic and plastic limit loading of the steel tube is calculated. The influence of frictional coefficient between steel tube and steel mould on the limit loading is discussed here. Finally, the calculating examples are illustrated.
