Thanks for the prompt reply.
I have had a look under both time/frequency viscoelasticity and *viscoelastic in the ABAQUS manual but this is not what I was after.
I probably should have made it more clear in my OP that I am trying to reproduce some test data which involves compression testing...
I'm new to ABAQUS and have a question on defining the material model.
Is it possible to make the elastic modulus of a material dependent on the strain rate experienced?
Are there any relevant documentation I should read?
Thanks
