Abstract Scope |
Edge crack initiation and growth in an aluminum sheet metal were investigated experimentally under overall uniaxial tension, plane strain tension and shearing loading conditions along its RD, DD and TD directions. A simple edge crack initiation criterion was formulated from the local strain measurement results. Nonlinear finite element analysis was carried out to analyze the deformation of the same aluminum sheet metal in a hole expansion operation using a quartic polynomial quartic yield function with the associate flow rule. The calibrated anisotropic plasticity model and edge crack initiation criteria were evaluated in terms of the predicted locations of necking and potential crack initiation in the hole expansion of the aluminum sheet metal. |
