WebConstitutive Models for Rubber XI - Bertrand Huneau 2024-06-07 Constitutive Models for Rubber XI is a comprehensive compilation of both the oral and poster contributions to the European Conference on Constitutive Models for Rubber. This 11th edition, held in Nantes (France) 25-27th June 2024, is the occasion to celebrate the 20th anniversary of Web1 feb. 2024 · In this study, constitutive models of polyurea and aluminum were established and fitted. We developed a 2nd-order Ogden rubber model to characterize the hyperelastic behavior of polyurea, and a 2nd-order Prony series of the generalized Maxwell model to characterize the viscoelastic behavior of polyurea.
