In calculating, power hardening function is used as the truestress - straincurve of materials.
计算时,板料的真实应力-应变曲线拟合为幂强化函数型。
2
There were drastic increase of truestress, drastic falling of truestress, steady stage and increase of truestress in its truestress-straincurve.
该材料的真应力-真应变曲线由应力激增阶段、应力下降阶段、稳态阶段和应力增加阶段组成;
3
As the rise of the strain rate, the feature of the truestress - truestraincurve changed from "flat" to "serration", and the thermal deformation softening feature was reinforced.
