Good substitute for cowper-symonds in Abaqus

Submitted by priyadd84 on
Hi all,
        I want to capture strain-rate behaviour of materials but unfortunately abaqus does not have Cowper-Symonds which is a widely used (simple) model. However johnson-cook is to complicate for me as not much details are available in literature as i am modeling bio-materials. Is there any good substitute for Cowper-Symonds models in abaqus. Thanks.
