| 摘 要： | 根据弹塑性力学全量理论及工程假设方法，给出了一种新的应力应变关系表述函数．应用该函数对复杂结构强度试验中弹塑性范围内直接检测到的应变数据进行应力转换，并结合双剪应力强度理论对结构强度进行判定．结果表明，该函数对解决较复杂工程结构强度试验中的应变转换具有较好的精确性和可实施性．

| Abstract: | A solution to make a convention between strain and data processing by the direct data from the complex in a range of elasticity and plasticity are given.Through establishing a new stress to gain another stress in structure strength test and making a judgment to apply the twin shear stress,the thesis offers a total theory and gets a mechanical premise.By this data processing,this solution has the greatest significance in solving the elasticity and plasticity of structure strength especially in aero-technical and aero-devices. |

| Keywords: | plasticity total theory constitutive relation elasticity plasticity twin shear stress |
