Failure Behaviour of Notched Sheet Specimen Under Plane Strain Deformation

The failure behaviour of notched AA5754 specimen subject to plane strain deformation is examined by the use of a heterogeneous finite element model. A ductile damage indicator triggered model is applied together with the use of element deletion technique for virtualization of fracture evolution. The predicted characteristics of the failure process under a wide range of triaxiality (0.33 to 2.5) fits well with those experimental observations in the literature.Copyright © 2006 by ASME
