Title: PTW modeling in xRage

Abstract

Preston-Tonks-Wallace Model (PTW), is a viscoplastic material model for very high strain rates (~10 11/s) and uses a Voce work hardening model. Strain rates above 10 9/s uses Wallace’s model of overdriven shocks in metals. PTW is applicable for broad range of strain rates (10 -3) -10 12).
