Many body interaction and cauchy relation for elastic constants

Modeling and Simulation of Deformable Elastic Body - Rigid Body Interaction

In this paper a procedure for simulating deformable elastic body rigid body interaction is presented. The interaction is described by multiple impacts during the dynamical process. An elastic body modeled as a 3D particles system is proposed, in response to the dynamic impacting force. The contact between particles is modeled with elastic springs. The expression for the spring elastic constants...

Nonequilibrium Ornstein-Zernike relation for Brownian many-body dynamics.

We derive a dynamic Ornstein-Zernike equation for classical fluids undergoing overdamped Brownian motion and driven out of equilibrium. Inhomogeneous two-time correlation functions are obtained from functional differentiation of the one-body density and current with respect to an appropriately chosen external field. Functional calculus leads naturally to non-Markovian equations of motion for th...

Radiative heat transfer: many-body effects

Heat transfer by electromagnetic radiation is one of the common methods of energy transfer between objects. Using the fluctuation-dissipation theorem, we have studied the effect of particle arrangement in the transmission of radiative heat in many-body systems. In order to show the effect of the structure morphology on the collective properties, the radiative heat transfer is studied and the re...
