Numerical Simulation of Hole-Flanging Process of Sheet Metal Thick Aluminium
Abstract: A hole-flanging operation on a flat circular sheet with a hole in the center is simulated by an incremental elastoplastic finite-element method, which incorporates strain-hardening and isotropy, with care taken to describe the boundary conditions of penetration, separation and the alternation of the sliding sticking state of friction. The simulation clearly demonstrates the processes of generation of […]
