Nonlinear elasticity theory plays a fundamental role in modelling the mechanical response of many polymeric and biological materials. Such materials are capable of undergoing finite deformation, and their material response is often characterised by complex, nonlinear constitutive relationships. Because of these difficulties, predicting the response of such materials to arbitrary loads requires numerical computation (usually based on the finite element method).

The steps involved in the construction of the required finite element algorithms are classical and straightforward in principle, but their application to non-trivial material models are typically tedious and error-prone. twist is a Python package that hopes to elegantly solve this problem.
