The capabilities of a new deformation model, MATMOD-4V, are demonstrated by comparison of computer predictions against independent data for high purity aluminum. In particular, model predictions of strain softening are presented and discussed. The predictive abilities of MATMOD-4V represent a substantial improvement over earlier versions of the MATMOD constitutive equations. The strength of the approach is illustrated by MATMOD-4V’s ability to predict deformation behaviors not explicitly built into the model.
