Sandia NLVEabq is a FORTRAN subroutine that defines a user supplied material model for the ABAQUS commercial finite element code. It must be compiled and linked with the ABAQUS libraries under the user supplied subroutine option of the ABAQUS executable script. The subroutine is an implementation of Sandia National Laboratories nonlinear viscoelastic material model that is used to analyze the thermomechanicat behavior of polymers. It is thermodynamically consistent, incorporates finite strains and is applicable to isotropic materials. The model is capable of predicting such diverse phenomena as stress relaxation, yielding, physical aging, thermal straining and enthalpy relaxation under arbitrary thermal and mechanical loading histories. This subroutine enables the ABAQUS finite element code to be sued for analyzing the performance of samples and structures that are made from polymers,
