Thermodynamically consistent nonlinear viscoplastic formulation with well-conditioned recovery of the inviscid solution: Theory and implicit integration algorithm with exact solution for the linear case
Khanh Nguyen, Victor J. Amores, Francisco J. Montans
In this work, a consistent viscoplasticity formulation is derived from thermodynamical principles and employing the concept of continuum elastic corrector rate. The proposed model…

On the network orientational affinity assumption in polymers and the micro-macro connection through the chain stretch
Victor Jesus Amores, Khanh Nguyen, Francisco Javier Montans
We question the network affinity assumption in modeling chain orientations under polymer deformations, and the use of the stretch measure projected from the right Cauchy-Green defo…

Data-driven, structure-based hyperelastic manifolds: A macro-micro-macro approach
Victor Jesús Amores, José María Benítez, Francisco Javier Montáns
In this paper we introduce a novel approach to obtain the stored energy density of rubber-like materials directly from experimental data. The model is structure-based, in which the…
