Journal ArticleDOI
Dynamics of entangled linear polymer melts: A molecular‐dynamics simulation
Kurt Kremer,Gary S. Grest +1 more
TL;DR: In this article, an extensive molecular-dynamics simulation for a bead spring model of a melt of linear polymers is presented, where the number of monomers N covers the range from N=5 to N=400.
Journal ArticleDOI
Molecular dynamics simulation for polymers in the presence of a heat bath.
Gary S. Grest,Kurt Kremer +1 more
TL;DR: An efficient and general algorithm for simulating polymers, which can be used for single, large chains as well as many-chain systems, and confirmed two theoretical results, namely the anomalous behavior of S(q) for rings and the ${t}^{0.54}$ power law for the motion of a monomer in a self-avoiding chain undergoing Rouse relaxation.
Journal ArticleDOI
Liquid-glass transition, a free-volume approach
Morrel H. Cohen,Gary S. Grest +1 more
TL;DR: In this paper, a theory of the underlying metastable phase, the amorphous phase, is developed, which is useful for describing the behavior of the viscosity of dense liquids and glasses.
Journal ArticleDOI
Computer simulation of grain growth—I. Kinetics
TL;DR: In this paper, a Monte Carlo procedure is applied to the study of grain growth in two dimensions, where the initial distribution of orientations is chosen at random and the system evolves so as to reduce the number of nearest neighbor pairs of unlike crystallographic orientation.
Journal ArticleDOI
Granular flow down an inclined plane: Bagnold scaling and rheology
Leonardo E. Silbert,Deniz Ertas,Gary S. Grest,Thomas C. Halsey,Dov Levine,Steven J. Plimpton +5 more
TL;DR: A systematic, large-scale simulation study of granular media in two and three dimensions, investigating the rheology of cohesionless granular particles in inclined plane geometries, finds that a steady-state flow regime exists in which the energy input from gravity balances that dissipated from friction and inelastic collisions is found.
