... at 25% below the surface of the plate. Experimental creep damage distributions were compared with computed versions using finite element method and damage mechanics analysis. Both multi-axial stress state and strain concentration in fine-grained HAZ appear to influence the formation and distribution...

... behavior of a high strength low toughness aluminim alloy. The assessment has been undertaken using the Gurson–Tvergaard continuum damage mechanics model that was calibrated against 25 mm -thick CT specimen data using a 2D plane strain finite element model. The calibrated model was then used...
