摘要
应用双剪应力强度理论对拉压异性材料制成的圆环进行了弹塑性应力分析 ,得到了弹性极限内压力、弹塑性极限内压力与拉压比的关系式 ,并举例说明了其在岩土材料抗拉强度测试中的应用。
In this article elasto plastic stress analyses on ring with different tensile and compressive strengths are conducted using generalized twin shear stress strength theory. The elastic limiting inner pressure and plastic limiting pressure, which are dependent on the tension compression ratio of the material, are obtained. The results are applied to determination of tensile strength of geomaterials.
