Journal ArticleDOI
Finite element implementation of incompressible, transversely isotropic hyperelasticity
TL;DR: In this article, a three-dimensional constitutive model for biological soft tissues and its finite element implementation for fully incompressible material behavior is presented, along with derivations of the stress and elasticity tensors for a transversely isotropic, hyperelastic material.
Journal ArticleDOI
A theory of finite viscoelasticity and numerical aspects
Stefanie Reese,Sanjay Govindjee +1 more
TL;DR: In this article, a nonlinear evolution law for finite deformation viscoelasticity was proposed, which is not restricted to states close to the thermodynamic equilibrium, and upon appropriate linearization, it can recover several established models of finite linear viscoels and linear velocities.
Journal ArticleDOI
Non‐smooth multisurface plasticity and viscoplasticity. Loading/unloading conditions and numerical algorithms
TL;DR: In this article, rate-independent plasticity and viscoplasticity in which the boundary of the elastic domain is defined by an arbitrary number of yield surfaces intersecting in a non-smooth fashion are considered in detail.
Journal ArticleDOI
A micro-mechanically based continuum damage model for carbon black-filled rubbers incorporating Mullins' effect
Sanjay Govindjee,Juan C. Simo +1 more
TL;DR: In this article, the problem of Mullins' effect in carbon black-filled rubbers is treated from a micro-mechanical viewpoint and a complete continuum constitutive model is developed.
Journal ArticleDOI
On the use of continuum mechanics to estimate the properties of nanotubes
TL;DR: In this paper, Bernoulli-Euler beam bending theory is used to infer the Young's Modulus, and the validity of such an approach using a simple elastic sheet model and show that at the nanotube scale the assumptions of continuum mechanics must be carefully respected to obtain reasonable results.
