| 摘 要： | 应用双剪统一强度理论,考虑材料的拉压异性和同性,推导了在内压和轴力联合作用下的厚壁圆筒的塑性极限载荷表达式在该表达式中,当其系数取不同的值时,就能得到按Tresca屈服准则、线性逼近的Mises屈服准则和双剪应力屈服准则进行计算的结果.

| Abstract: | The limit loading formulae of thick-walled tube with differential strength in tension and compression are derived in the twin shear unified strength theory under the combined actions of both an inner pressure and axial force.In these formulae the results calculated respectively in Tresca criterion,linear approximate Mises criterion and twin shear stress yielded criterion can be obtained as its different coefficient values are selected. |

| Keywords: | Twin shear unified strength theory thick-walled tube yield criterion limit load |
