The sheet metal forming by shearing is one of the most used processes in industries. The reliability of the obtained parts depends on geometrical parameters (shape of the tools, punch radius, clearances, velocity...) and materials properties (metal behavior, friction...). In this paper, two experimental parameters are investigated: the punch – die clearance and the punch velocity. A 0.65 mm thickness sheet of a non-oriented full-process Fe-(wt.3%)Si is used. The analyses are done through the load-stroke curve and the height repartition of different defects on the part edge. A numerical approach is proposed to simulate the shearing process and to handle the ductile fracture (which is performed using Abaqus/Explicit software). This work is based on a non-iterative explicit algorithm combined with a mesh adaptivity method (Arbitrary Lagrangian Eulerian formulation). The Gurson–Tvergaard–Needleman model is then used to describe the cut edge profile occurring during the process.
