In the following, the collective dynamical behaviour of many convex and non-convex polyhedral bodies in space is described. To be able to simulate a high number of bodies, methods from Molecular Dynamics (MD) are frequently used. Here these methods are combined with collision detection methods and contact formulations adopted from Multibody Systems (MBS). The used methods are presented briefly ...

The effect of mass on gas/organic-surface energy transfer is explored via investigation of the scattering dynamics of rare gases (Ne, Ar, and Kr) from regular (CH3-terminated) and omega-fluorinated (CF3-terminated) alkanethiol self-assembled monolayers (SAMs) at 60 kJmol collision energy. Molecular-beam scattering experiments carried out in ultrahigh vacuum and molecular-dynamics simulations ba...

This paper focuses on the optimization of initiating dimensions of groove bearing in association with de- sired design of vehicle’s front structure which is made up of low carbon steels in the case of frontal collision. Axial bearing analysis is done numerically using nonlinear finite element code LS-DYNA. In this analysis, changes of two main parameters including measure of energy absorp...

We demonstrate the necessity of using realistic stellar models taken from stellar evolution codes, as opposed to polytropes, for starting models in smoothed particle hydrodynamics calculations of collisions between main sequence stars. Evolved stars have mean molecular weight gradients, which affect their entropy profiles and therefore affect how they react during a collision. The structure of ...

Collision Detection or interference detection has been studied extensively in robotics, computer graphics, physically-based modeling, molecular modeling, visualization and virtual environment. Predominantly, the input to a collision detection algorithm comprises large and complex geometric object either as static or dynamic object within the environment. The term collision detection refers to a...
