Together with my student Damien Ollion, we have converted the finite-strain viscoelastic UMAT originally developed with Florian Gouhier into a VUMAT for Abaqus/Explicit. The implementation reproduces the constitutive model of Reese and Govindjee (1998) for a generalized Maxwell model and includes the following features: A comprehensive How-to-use.pdf document is provided. It presents the constitutive equations, illustrates the...

This is the python routine I used to calculate the linear viscoelasticity (storage and loss shear moduli) of worm-like microstructures define in the paper on linear viscoelasticity of IPNs. This routine may be used for any two-phase materials with the microstructure of your choice.You need two input.txt (phase1.txt and phase2.txt) files for the behavior constitutive...

The linear viscoelasticity of several carbon-black filled SBRs were characterized by DMA tests on a DMAQ800 dynamic uniaxial tension machine from TA. Figure 1. Storage modulus and damping factor of several carbon-black filled SBRs measured by uniaxial tension DMA tests. Materials are made of the same gum and filled with 0, 5, 30, 40, 50...
