Hi all ...

I am using a material which is rate dependant (elastic modulus increases with increase in strain rate), though i dont want to use viscoelastic model that comes with Abaqus as i am not looking into the relaxation and creep aspect. I am monotonously loading the material till failure so no talk of relaxation as i am not loading the material in fatigue.

Assuming that i have a continuous function which takes in the strain-rate and gives out elastic modulus, the strain-rate i should get from each element in each increment based on that the function will give a new young,s modulus which i will update the same element for the next increment. This procedure is done for all the elements in the mesh.

How this procedure can be implemented? I am using Abaqus/Explicit. Thanks all.
