Dear Itachi, Deal.II is significantly different than abaqus in the fact that you easily write you own equation and solve from it using whatever mean you find necessary. However, it does not come readily built with a library of physical solvers or constitutive laws. Consequently, you will have to build your own weak form for your problem of interest (although this can be made much easier with automatic differentiation facilities)..
So consequently, any user material can be defined in deal.II, but it is significantly different than what you would obtained using a UMAT file for instance.
