Hello, why is it shear stress vs gamma strain, and not stress vs strain?

[@nirajchawake]

Our objective is to establish a connection between stress and strain behavior and the motion of dislocations. In this context, we understand that dislocations glide or slip along specific planes, resulting in shear strain. These movements are governed by the shear stress acting on these glide planes. Therefore, for simplicity, we concentrate on investigating shear stress and shear strain in this scenario.

Hi i dont get what happen if there is an incoherent phase, what effect does it have on the dislocation motion, does a dislocation can travel through it ? And thus what is the effect on the hardening if there is a non coherent phase ?
