The stress equilibrium equations although derived for the deformed state of that material did not entail any assumptions about the material or the type of deformation it encurs. We learned that for most situations the stress equilibrium equations are indeterminate and we can t solve for material stresses directly from these equations.

To initiate a deformation process a critical resolved shear stress (CRSS) must be exceeded in a slip plane (and in particular in slip direction) in order to shear off the lattice plane. Due to the binding forces between the atoms one can make theoretical predictions what critical shear stress is necessary.
