What is it about?
The dislocation slip is an important physical phenomenon in metals. The CRSS is the critical value of shear stress when dislocations begin to slip in metal. We have established a physical-based temperature-dependent CRSS model in pure shear mode for the first time.

Why is it important?
We define rules for determining the effect of temperature on the critical resolved shear stress. It is assumed that there is a maximum constant value for the maximum storage of energy per unit volume when dislocation slip started in metal, which including the elastic energy and the corresponding equivalent heat energy. There is an equivalent relation in elastic deformation energy and the corresponding heat energy at temperature T.
Perspectives
Writing this article was a great pleasure as it has co-authors with whom I have had long standing collaborations. This article is also an application of temperature-dependent modeling method proposed by our team.
