Abstraet--A laser speckle technique, together with a computer-based image processing system, was used to measure the extent of the elastic-plastic boundary ahead of a static mode 1 crack under small-scale yielding. The technique used a simple optical set-up and did not require surface contact with t

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
The present paper describes a simple mathematical mode? to predict tip opening displacement in notches and removes anomalies that arise when the earlier theories of sharp cracks are. applied to notches. The evaluation of plastic zone size, stress intensity factor and tip opening displacement in notc
Under the conditions of constant nominal applied stress. increasing notch root radius causes an increase in the number of cycles to initiate a fatigue crack at a notch root. An explanation of the effect is given in terms of the effective stress concentration factor of the notch. Data are presented w
