fenics-constitutive

For some examples which are using legacy-FEniCS you may look on the old master branch legacy code

The new and improved version of fenics-constitutive which has the goal of simulating mechanical problems in FEniCSx with nonlinear consitutive models like plasticity, damage, etc. Everything is still a work in process, but from this projct you might expect:

  1. An interface for constitutive models for small strain increments (and some examples for such models)
  2. Solvers for mechanical problems which can use any constitutive model that follows our interface design
    • This means that YOU may write constitutive models in any programming language as long as you can bind that code to Python and this code takes numpy.ndarray as parameters.
  3. Solvers that account for large deformations via an objective stress rate.
  4. A documentaion explaining the interface design and tutorials on how to write your own constitutive models.

More to follow soon!
