Star 3

FEniCSx finite element (FEM) examples for computational viscoelasticity of finite-deformation elastomers, using internal-variable constitutive models with nonlinear elasticity and viscosity. Includes pedagogical boundary value problems (uniaxial and single-edge-notch) and Colab-ready Jupyter workflows.

Star 0

Convex signed singular value neural network (CSSV-NN) for isotropic hyperelasticity: learns a strain-energy density from stress data alone, with objectivity, isotropy, polyconvexity and thermodynamic consistency guaranteed by construction rather than by penalty terms. Reference implementation for Geuken et al., JMPS 203 (2025).
