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

Abatraet-In this paper, the ductile plastic damage behaviour of weld heat alkcted zone (HAZ) is studied by use of continuum dama mechanics (CDM). Based on a continumn damage variable, D, the effective stress concept and tpf" e thermodynamics, a general continuum damage model for isotropic ductile fr
A new plastic-damage constitutive model for cyclic loading of concrete has been developed for the earthquake analysis of concrete dams. The rate-independent model consistently includes the effects of strain softening, represented by separate damage variables for tension and compression. A simple sca
