Modeling the viscoelastoplastic behavior of amorphous glassy polymers
Constitutive equations are derived for the viscoelastoplastic response of amorphous glassy polymers at isothermal loading with small strains. A polymer is treated as an ensemble of cooperatively relaxing regions (CRR) which rearrange at random times as they are thermally agitated. Rearrangement of CRRs reflects the viscoelastic response of the bulk medium. At low stresses, CRRs are connected wi...
متن کاملMechanical Properties of Graphene/Epoxy Nanocomposites under Static and Flexural Fatigue Loadings
In the present study, the effect of various weight fractions of graphene nanoplatelet (GPL) on flexural fatigue behavior of epoxy polymer has been investigated at room temperature and generally the temperature was monitored on the surface of specimen during each test. The flexural stiffness of grapheme nano-platelet/epoxy nanocomposites at 0.1, 0.25 and 0.5 wt. % as a main effective parameter o...
متن کاملSimulating the mechanical response of amorphous solids using atomistic methods
The study of elasticity, plasticity and failure in non-crystalline solids has greatly benefitted from the application of atomic scale simulation. This “colloquium paper” reviews the ways in which a variety of computational approaches have been used to elucidate the atomic scale phenomena that control the mechanics of amorphous solids. The constitutive theories that have been developed for descr...
متن کاملPhysics of Amorphous Solids: their Creation and their Mechanical Properties
In this short review I summarize some progress achieved in my research group regarding the glass transition and the mechanical properties of the resulting amorphous solids. Our main concerns were on the one hand to understand the extreme slowing down over a narrow range of temperatures which results in a viscosity so high that the materials behave as solids under small mechanical strains. On th...
متن کاملMaterials modeling by design: applications to amorphous solids.
In this paper, we review a host of methods used to model amorphous materials. We particularly describe methods which impose constraints on the models to ensure that the final model meets a priori requirements (on structure, topology, chemical order, etc). In particular, we review work based on quench from the melt simulations, the 'decorate and relax' method, which is shown to be a reliable sch...
