Boltzmann Model for viscoelastic particles: asymptotic behavior, pointwise lower bounds and regularity

چکیده
We investigate the long-time behavior of a system of viscoelastic particles modeledwith the homogeneous Boltzmann equation.We prove the existence of a universal Maxwellian intermediate asymptotic state with explicit rate of convergence towards it. Exponential lower pointwise bounds and propagation of regularity are also studied. These results can be seen as a generalization of several classical results holding for the pseudo-Maxwellian and constant normal restitution models.

Time-asymptotic Behaviour of Weak Solutions for a Viscoelastic Two-phase Model with Nonlocal Capillarity
Abstract. The aim of this paper is to study the time-asymptotic behaviour of weak solutions of an initial-boundary value problem for a viscoelastic two-phase material with capillarity in one space dimension. Therein, the capillarity is modelled via a nonlocal interaction potential. Based on the existence and regularity results of [5], we analyze the time-asymptotic convergence of the strain-vel...
متن کاملAnalysis of Five Parameter Viscoelastic Model Under Dynamic Loading
The purpose of this paper is to analysis the viscoelastic models under dynamic loading. A five-parameter model is chosen for study exhibits elastic, viscous, and retarded elastic response to shearing stress. The viscoelastic specimen is chosen which closely approximates the actual behavior of a polymer. The module of elasticity and viscosity coefficients are assumed to be space dependent i.e. f...

متن کاملSimulation of Foaming and Deformation for Composite Aluminum Foams
In this study, at the first stage, the rupture criterion of bubbles wall in Aluminum metal foam liquid was investigated by using Lattice Boltzmann. The two phases modeling were accomplished by using a modified Shan-Chen model. This model was run for several bubbles in A356+3wt.%SiC melt system. Then, bubbles morphologies (virtual metallographic) for A356+3wt.%SiC foams were simulated. Results s...
متن کاملPointwise a Posteriori Error Estimates for Elliptic Problems on Highly Graded Meshes
Pointwise a posteriori error estimates are derived for linear secondorder elliptic problems over general polygonal domains in 2D. The analysis carries over regardless of convexity, accounting even for slit domains, and applies to highly graded unstructured meshes as well. A key ingredient is a new asymptotic a priori estimate for regularized Green's functions. The estimators lead always to uppe...
