The distribution of dislocations in the vicinity of a mode I crack tip is formulated based on the observation of a single crystal specimen of aluminium by transmission electron microscopy (TEM). Closed form expressions of the dislocation density function and the dislocation-free zone (DFZ) condition

A method for the crack tip analysis of a tensile loaded crack (mode I) due to yielding of the material is developed. The stress/strain distribution within the plastic zone, as well as size of the plastic zone are presented. The development is based on the energy interpretation of the strain hardenin
In this paper, based on physical meanings of hysteresis loops denoting a relationship between loads and strains near the fatigue crack tip, variations of the tensile plastic zone in loading and the compressive plastic zone in unloading as well as the effects on acceleration, retardation and non-prop
