Abstract

A viscoplastic constitutive theory containing an internal damage variable, representing void volume fraction, is used to model deformation and ductile failure of smooth tensile bars under high rate loading. In the simulations the position of the neck is not always along the centerline, but instead is found to vary as a function of the loading rate. Computed elongation at instability and elongation at fracture is compared to data found in the literature. The theory correctly predicts the increase in elongation with increasing rate of deformation.
