The modified rainflow counting method can take out all the full cycles truly existing in the real stress-strain response, so it is a more reasonable cyclic counting method than the traditiona…
此外，对于现有的两种利用有效系数模拟应力-应变响应的方法也进行了讨论，并提出了修正有效系数法。
Most of the existing models for borehole wall stress are based on plane strain hypothesis. So some errors may be generated as compared with the real stress state of rock.
现有井壁围岩应力求解模型大都基于平面应变假设，相对岩石真实应力状态会有一定的误差。
Through the experiment, the relation formula of real stress, real strain and the curve of stress and strain are achieved.
通过实验得到真实应力的关系式及真实应变关系式，进而得到真实应力-应变曲线。
