We do this with MOOSE (whih is built on libMesh)... Including having the ability to directly utilize Fortan Abaqus umats with our nonlinear mechanics system... however our code is not currently open sourced.
You might still be able to get it... email me directly if you're interested and I'll send you more info. However, this should let you know that it is possible to do it with libmesh. We have extremely complex material models (like crystal plasticity fully coupled to several other PDEs) that we're solving without issue using libMesh. If you have any specific questions, I can probably help. I think that there is an example of doing linear elasticity in the libmesh examples now... I would probably start there...
