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

Crack length an d plastic zone size measurements were made on a limited number of mild steel tensile specimens of ASTMGS No.3.5 and No. 7.0 grain size for various stress amplitudes and various mean stresses. The data are in agreement with the predictions of Silby, Cottrell and Swinden concerning the
