Implement Shear-rate dependent stiffness in material model (fabric)

[AlexanderC]

Hi,

I am using the Fabric material model for my analysis and would like to implement different strain-stress relationships for different shear rates in uniaxial_2 direction. Can anyone give me a hint how to implement this?
I looked up the Abaqus help, but that didn't help.

This is how my model looks like now:

** FABRIC_test
**
*Material, name=Fabric_test
**
*Density
1e-09,
*Damping, Beta=3e-6
*Fabric, stress free initial slack=yes
*Uniaxial, Component=1
*Loading data, regularize=off
0.000000e+00, 0.000000e+00
2.0000e+03, 1.000000e+00
*Uniaxial, Component=2
*Loading data, regularize=off
0.000000e+00, 0.000000e+00
2.0000e+03, 1.000000e+00
*Uniaxial, Component=shear
*Loading data, regularize=off
xxx,xxx
xxx,xxx

Thanks in advance,

Alex
