Abstract
Time-dependent relaxation processes continue after the forming operations of sheet metal components. Hence, properties and shape of the part will evolve with time. In order to evaluate kinetics at the low deformation rates that are associated with stress relaxation, a bent beam relaxation test is chosen. The kinetics during stress relaxation are fitted using an elasto-viscoplastic model. Using the resulting kinetic law, a user material subroutine for ABAQUS is developed to examine the relaxation of aluminum sheet metal.
