[en] Many important problems in solid mechanics involve non-trivial constitutive models that are difficult to express in variational form. It is therefore challenging to express these problems in domain-specific languages that work at the variational form level. We introduce a framework for FEniCSx / DOLFINx that allows for the straightforward implementation of a wide range of constitutive models. The application of the framework is demonstrated by implementing a von Mises elastoplastic material model with hardening using JAX and Numba software.
