I am currently doing some research into total wrist implants and one of the components is UHMWPe. After numerous simulations in Abaqus that kept producing large errors in the UHMWPe component I started to research your hybrid model. I have manage to find a LS-DYNA subroutine for your hybrid model on the exponent website but I have yet to find an Abaqus version. Currently, I don't have any access to LS-DYNA so I am having to use Abaqus regardless. I was wondering if you could provide a download link for an abaqus subroutine of this model? Any help with this is much appreciated as your model is very interesting to myself and my colleagues.
