A stress component in a system which consists of unequal principal stresses. ... Deviatoric stresses control the degree of body distortion.

What is the importance of deviatoric stress?

The experimental results showed that the higher deviatoric stress level accelerated the damage development caused by the unloading effect and improved the expansion rate of the internal cracks, which led to a higher radial strain rate, total strain, and acoustic emission hits.

What is Deviatoric stress?

Deviatoric stress is the difference between the stress tensor σ and hydrostatic pressure tensor p acting on the rock or soil mass.
