What is 'anelasticity' 🧑‍🔧

Welcome my friend! The purpose of this article is explain “What is 'anelasticity'” by answering common doubts.

And the quick answer is…

Deviation from a proportional relationship between stress and strain.

Anelasticity is a property of materials that describes their behaviour when undergoing deformation.

Its formal definition does not include the physical or atomistic mechanisms but still interprets the anelastic behaviour as a manifestation of internal relaxation processes.

These are questions that people still ask:

Anelasticity

What is the critical stress for anelasticity...

Anelasticity begins at a much smaller critical stress σ e − a, typically less than 0.1 σ y. Therefore, nonlinearity and dislocation motion is significant throughout most of the pre-yield stress range. Figs. 6 and some cases of Fig. 8 show the development of a slight negative offset strain in the early, low-stress LU loops.
