Interatomic force in systems with multibody interactions.
The system of particles (atoms) interacting via multibody interatomic potential of general form is considered. Possible variants of partition for the total force acting on a single particle into pair contributions are discussed. Two definitions for the force acting between a pair of particles are compared. The forces coincide only if the particles interact via pair or embedded-atom potentials. ...
متن کاملMultibody Interactions in Coarse-Graining Schemes for Extended Systems
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...

متن کاملRevolute joints with clearance in multibody systems
A computational methodology for dynamic analysis of multibody mechanical systems with joint clearance is presented in this work. Clearances always exist in real joints in order to ensure the correct relative motion between the connected bodies being the gap associated to them a result of machining tolerance, wear, and local deformations. Clearance at different joints is the source for impact fo...
