Abstract

Authors suggest a method to compute the parameters in the Ramberg-Osgood constitutive relation, which when used in the Hutchinson-Rice-Rosengren stress formula in front of the crack leads to a good agreement with the stress distribution computed numerically. The method is tested by finite element calculations.
