In this paper, a phenomenological finite-strain thermomechanically consistent constitutive theory is reported to describe the thermomechanical response of a thermoplastic polymer for its use in a Sheet Molding Compound (SMC) over large ranges of strain rates and temperatures. This generalized framework addresses non-isothermal viscoelasticity and viscoplasticity, and self-heating in a straightforward manner to predict response under complex loading scenarios.
