N2 - This study focuses on modeling and analyzing sheet blanking process of Magnesium alloy sheet (AZ31) using finite element method at various temperatures. The computational analysis is then compared with the results obtained through the experimental setup. In the finite element model fracture initiation and the shape of the blanked edge are influenced by the value of critical damage criteria (C). The value of critical criteria is determined and compared using the ductile fracture criteria proposed by various researchers by varying various process parameters and temperature. The effect of temperature and process parameters on the geometry of the blanked edge including burr, fracture zone, shear surface and rollover has been investigated. Moreover, numerical predictions were compared with the experimental results.
