High resolution fatigue crack growth analysis of crack closure and slip irreversibility using digital image correlation
Crack closure and slip irreversibility in the fatigue crack growth of 316L stainless steel were investigated using digital image correlation (DIC). A polycrystalline and a oriented specimen were tested to study mode I fatigue crack growth, while oriented specimens were used to study mixed mode (I …

Fatigue crack growth (FCG) modeling in the presence of nano-obstacles
… loading. A method is developed to quantify the irreversibility of slip, and calculate it as a function of the twin lamella thickness and crack-tip to twin lamella spacing. Subsequently, atomistically calculated slip irreversibility is utilized in dislocation dynamics crack growth simulations to …

Advanced experimental measurements of heterogeneous strain and temperature change in metals
… the two cases. From these strain fields, the slip irreversibility, the difference between forward and reversed strains at the crack tip, was quantitatively measured. The high temperature case had an order of magnitude higher amount of slip irreversibility. Slip irreversibility measurements …
