An anisotropic thermo-mechanically coupled constitutive model for glass fiber reinforced polyamide 6 including crystallization kinetics: material subroutines

This dataset contains the Abaqus user material subroutines (UMAT/UMATHT) of models:

M. Reuvers, C. Dannenberg, S. Kulkarni, M. Johlitz, A. Lion, S. Reese, and T. Brepols. An anisotropic thermo-mechanically coupled constitutive model for glass fiber reinforced polyamide 6 including crystallization kinetics.

The included input files comprise uniaxial tension tests with one and 125 elements, as well as the plate with hole for the thermo-mechanically coupled boundary value problem with a cooling rate of 100 K/s in Sec. 4.3 of the corresponding publication.

The codes are written in FORTRAN. All derivates are computed by AceGen and are, thereafter, exported to FORTRAN.
