Hi ,

I am using abaqus to model a non linear viscoelastic polymer. I have input my relaxation test data as shear data for viscoelastic properties. I have added hyperelastic properties with uniaxial stress strain data as well.
However I find that the results of output stress strain only match for a constant strain rate.
Would it be possible to have the strain rate dependence reflect on the output.I would like to see the stress strain plot changing with changes in the strain rate.

What are the boundary conditions of an elastic rod at a clamp moving on a perfectly smooth and rigid circular profile?

The tangential shear at the clamp turns out to not be null!

hi 

I'm a beginner in abaqus and I started to simulate an multiscale analysis, I model both micro and macro scales and even homogenization part for micro scale outputs, but I couldn't perform a relation between two scales. i know the parts of the code, but i can't call phyton from fortran subroutine.

could any expert guide me how to overcome this problem?

thanks
