As the rise of the strain rate, the feature of the true stress - true strain curve changed from "flat" to "serration", and the thermal deformation softening feature was reinforced.
随应变速率升高，真应力-真应变曲线特征从“平缓”型向“锯齿”型转变，材料热变形软化特征增强。
When it was tensile failure, the curve of stress-strain relationship was softening and the reinforcement only increased the angle of internal friction of soil.
当发生拉断破坏时，其应力-应变曲线为软化型，此时加筋仅增加土体的粘聚力分量；
Finally, influences of constitutive parameters, such as elastic and softening moduli, and specimen length on complete stress-strain curve are investigated.
