Journal ArticleDOI
A self consistent approach of the large deformation polycrystal viscoplasticity
TL;DR: In this paper, a large deformation viscoplastic polycrystal theory is formulated and a self-consistent approach is developed, where each grain is assumed to be a single ellipsoidal inclusion in a homogeneous equivalent medium.
Journal ArticleDOI
Influence of temperature and strain rate on the mechanical behavior of three amorphous polymers: Characterization and modeling of the compressive yield stress
TL;DR: In this paper, a cooperative model based on a strain rate/temperature superposition principle was proposed for compressive yield stress analysis of polycarbonate, polymethylmethacrylate, and polyamideimide.
Journal ArticleDOI
Thermal conductivity and tensile response of defective graphene: A molecular dynamics study
TL;DR: In this article, the effects of point vacancy, Stone-Wales and bivacancy defects on thermal conductivity and tensile response of single-layer graphene sheets are studied using classical molecular dynamics (MD) simulations.
Journal ArticleDOI
A formulation of the cooperative model for the yield stress of amorphous polymers for a wide range of strain rates and temperatures
TL;DR: In this article, a new formulation of the cooperative model of Fotheringham and Cherry is proposed, where the final mathematical form of the model is derived according to the strain rate/temperature superposition principle of the yield stress.
Journal ArticleDOI
Modeling and validation of the large deformation inelastic response of amorphous polymers over a wide range of temperatures and strain rates
TL;DR: In this article, a robust physically consistent three-dimensional constitutive model is developed to describe the finite mechanical response of amorphous polymers over a wide range of temperatures and strain rates, including the rubbery region and for impact loading rates.
