Almtraet-A cohesive damage zone model of the Dugdale-Barenblatt type is presented to explore the effects of microscopic damage on a macroscopic crack in ductile materials. A semi-intinite macrocrack in a power-law plastic material under antiplane shear (mode III) is considered. The microscopic damag
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
