Numerical Simulation Research for Hole-flanging Based
on DYNAFORM Software
Abstract: The hole-flanging process of a typical air-condition panel part was simulated numerically by using the
dynamic explicit non-linear finite element software eta/DYNAFORM. Through the simulation, the influences of strain
hardening exponent n, coefficient of normal anisotropy r and flanging coefficient K on hole-flanging formability were
analyzed. Then the resultant curves of thinning rate and n value or r value were made. The simulation result has the
directive function for choosing material.
