Abstract:A forward open cold extrusion process is evaluated to reveal the sensitivity of forming load to numerical factors including number of total degrees of freedom, time step size and mesh size. The allowable reduction of area was examined by varying number of finite elements and the total solution steps to determine the reliability, in which the results are affected significantly by the positions of the lowest and highest nodal points in contact with the die. An investigation of the oscillations of the forming loa… Show more
