This ABAQUS UHYPER subroutine implements the hyperelastic energy density derived in Journal of the Mechanics and Physics of Solids 122 (2019), 364–380 for the macroscopic elastic response of non-Gaussian elastomers weakened by an isotropic and non-percolative distribution of equiaxed pores. This result is valid for any choice of I1-based incompr…
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.
