victorlefevre/UHYPER_Lefevre_Lopez-Pamies
This ABAQUS UHYPER subroutine implements the hyperelastic energy density derived in Journal of the Mechanics and Physics of Solids 99 (2017), 438-470 for the macroscopic elastic response of isotropic and incompressible filled elastomers. The results applies to general non-percolative isotropic distributions of stiff inclusions, stiff interphases, and stiff occluded rubber. This result is valid for any choice of I1-based incompressible energy density characterizing the non-Gaussian isotropic elastic response of the underlying elastomer. The present subroutine is implemented for the choice of strain energy density proposed in Comptes Rendus Mecanique 338 (2010), 3–11.
