|Cyclic anelasticity of metals|
vol. 52 (2014), no. 6, pp. 353 - 359
The mechanics of a solid body is based on Hooke’s law. The non-linearity of the stress-strain curve in cyclic loading begins at much lower stress values than at the static yield stress point. A sensitive measurement of hysteresis loops led to discovering the anelastic strain processes below the yield stress and also below the fatigue limit. In this paper, the anelasticity limit is defined – the limit between reversible and irreversible strains – which is in compliance with the fatigue damage cumulation.
