The second shear strain gradient and the function reflecting the effectofstrainrate are introduced into the yield function of classical elastoplastic theory.
在经典弹-塑性理论的屈服函数中引入应变梯度及考虑应变率效应的函数。

The authors suggest that this effect is due to the change in the strainrateof crack tip metal thus altering the thermodynamics of crack onset and growth.
On the base of above appoints, the slow strainrate test was used to study the effectof prestraining on the SCC susceptibility of X70 pipeline steel in simulate soil media.
