## Abrbret--Although it is markedly dependent on both the stress at the cohesive zone tip and the dispkummt at the crack tip, the cohesive zor~ size at the critical stage of crack extension is shown to be relatively insensitive to the deteikd form of the force law &scribirIg the non-iinesrity of m
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
Consideration is given to the development of a general theory for the determination of the structure in the vicinity of the tip of a crack within an isotropic elastic solid. The basis of the model is the presence of a Barenhlatt-type zone, in which cohesive stresses act, thereby allowing non-linear
