Experimental estimation of the heat energy dissipated in a volume surrounding the tip of a fatigue crack [PDF]
Fracture and Structural Integrity, 2016 Fatigue crack initiation and propagation involve plastic strains that require some work to be done on the material. Most of this irreversible energy is dissipated as heat and consequently the material temperature increases.

Dynamic Strain Evolution around a Crack Tip under Steady- and Overloaded-Fatigue Conditions
Metals, 2015 We investigated the evolution of the strain fields around a fatigued crack tip between the steady- and overloaded-fatigue conditions using a nondestructive neutron diffraction technique.

A model to quantify fatigue crack growth by cyclic damage accumulation calculated by strip-yield procedures [PDF]
Fracture and Structural Integrity, 2017 Elber's hypothesis that DeltaKeff can be assumed as the driving force for fatigue crack growth (FCG) is the basis for strip-yield models widely used to predict fatigue lives under variable amplitude loads, although it does not explain all load sequence ...

Influence of strain-rate and strain cycling on fatigue crack-tip plasticity
, 1984 A general relationship for the calculation of strain rates at the fatigue crack tip was derived. This relationship is applied to predict the effect of strain rate and strain cycling on the dimensions of the monotonic and cyclic plastic zones. Strain rates are independent of the applied DELTA K or K//m//a//x, but depend on frequency and stress ratio R ...

Strain-gradient effect on the crack tip dislocations density
Frattura ed Integrità Strutturale, 2020 In this study, the influence of a material’s plastic properties on the crack tip fields and dislocation density behavior is analytically and numerically analyzed using the conventional mechanism-based strain-gradient plasticity (CMSGP) theory established using the Taylor model.
