Finite Element Simulation of Shearing Force in Disc Slitting Process

Based on the principle of disc slitting process, a 3D model of the disc slitting process for galvanized sheet was established by using DEFORM-3D software, and the deformation, fracture and material effective stress of galvanized sheet were analyzed. The surface morphology of numerical simulation is in good agreement with the actual result. The curve of shearing force was obtained and well matched with the change rule of slitting process. Compared with the theoretical calculation result, the simulation result is reliable and can provide a reference for the calculation of shearing force.
