Shear flow effects on phase separation of entangled polymer blends [PDF]
, 1998 We introduce an entanglement model mixing rule for stress relaxation in a polymer blend to a modified Cahn-Hilliard equation of motion for concentration fluctuations in the presence of shear flow.

Traffic flow models with ‘slow‐to‐start’ rules [PDF]
Annalen der Physik, 1997 AbstractWe investigate two models for traffic flow with modified acceleration (‘slow‐to‐start’) rules. Even in the simplest case vmax = 1 these rules break the ‘particle‐hole’ symmetry of the model. We determine the fundamental diagram (flow‐density relationship) using the so‐called car‐oriented mean‐field approach (COMF) which yields the exact ...

Space-time discontinuous Galerkin finite element method with dynamic grid motion for inviscid compressible flows. Part II. Efficient flux quadrature [PDF]
, 2001 A new and efficient quadrature rule for the flux integrals arising in the space-time discontinuous Galerkin discretization of the Euler equations in a moving and deforming space-time domain is presented and analyzed. The quadrature rule is a factor three

Traffic flow and safety analysis
Theoretical and Applied Mechanics Letters, 2018 Traffic rule is a key factor affecting traffic flow and safety. We develop our models, including the cellular automata traffic flow model as well as the linear regression one, aiming at calculating traffic flow and evaluating safety conditions with ...

Journal of the Mechanical Behavior of Materials, 2018 This article investigates the differences between the Aifantis and Gurtin-Anand strain gradient plasticity. The fact that Gurtin-Anand strain gradient plasticity is richer than the Aifantis strain gradient plasticity provides a basis for which we could ...

Interparticle friction leads to non-monotonic flow curves and hysteresis in viscous suspensions [PDF]
, 2019 Hysteresis is a major feature of the solid-liquid transition in granular materials. This property, by allowing metastable states, can potentially yield catastrophic phenomena such as earthquakes or aerial landslides.

Balanced-Viscosity solutions for multi-rate systems [PDF]
, 2014 Several mechanical systems are modeled by the static momentum balance for the displacement $u$ coupled with a rate-independent flow rule for some internal variable $z$. We consider a class of abstract systems of ODEs which have the same structure, albeit

A Mixed-Flow Cellular Automaton Model for Vehicle Nonstrict Priority Give-Way Behavior at Crosswalks
Journal of Advanced Transportation, 2020 The vehicle nonstrict priority give-way behavior (VNPGWB) is a common part of traffic interaction between motorized and nonmotorized vehicles in many countries. This study proposes a mixed-flow cellular automaton model to simulate the passing of vehicles

Flavor ordering of elliptic flows at high transverse momentum [PDF]
, 2002 Based on the quark coalescence model for the parton-to-hadron phase transition in ultra-relativistic heavy ion collisions, we relate the elliptic flow ($v_2$) of high $\pt$ hadrons to that of high $\pt$ quarks.
