Abstract:

A viscoplastic formulation based on Perzynas elasticviscoplastic theory and the Sandler and Rubin CAP75 plasticity model was extended to included a tension cutoff mechanism. The mechanism employs separate fluidity parameters for the dilatational and deviatoric stress releases. A parameter identification study was performed to determine the sensitivity of the parameters and means of determining them from experimental data. Author
