Multi-body dynamics is a powerful engineering tool which is becoming increasingly popular for the simulation and analysis of skull biomechanics. This paper presents the first application of multi-body dynamics to analyse the biomechanics of the rabbit skull. A model has been constructed through the combination of manual dissection and three-dimensional imaging techniques (magnetic resonance ima...

This paper reports the first results of a new interface between the multi-body simulation software SIMPACK Rail and Kalker’s wheel-rail contact software CONTACT. The main benefit is in the more accurate distributions of shear stress and micro-slip in the contact area, that together form the primary inputs to wear calculations. Further benefits of the interfacing reside in the ability to perform...

Energy density and energy flux was introduced along Takesue’s method. Particle energies were localized at particle positions using Dirac delta function. The energy density was connected with the energy flux by continuity equation. New method was proposed to deal with multi–body interaction. Consequently, the energy current between particles could be calculated even if the multi–body interaction...

We develop the multi-layer multi-configuration time-dependent Hartree method for bosons (ML-MCTDHB), a variational numerically exact ab initio method for studying the quantum dynamics and stationary properties of general bosonic systems. ML-MCTDHB takes advantage of the permutation symmetry of identical bosons, which allows for investigations of the quantum dynamics from few to many-body system...

In [12, 14] coarse-graining schemes for stochastic many body microscopic models focusing on equilibrium stochastic lattice systems were developed and furthermore, the accuracy of the coarse-graining schemes was estimated in terms of information loss between the exact and approximate coarse-grained Gibbs measures. The relative entropy estimates are given in terms of a small parameter . In this p...

in this study the operations of melting of au15ag40 nanoalloy have been studied using the molecular dynamic simulations through the gupta multiparticle potential and the nonergodicity of simulations is eliminated by the multiple histogram method. the melting characteristics are determined by the analysis of variations in the potential energy. the calculations indicate that the melting of au15ag...
