Rigid-Body Contact Using Finite Particle Method

Abstract:

Using the recently proposed Finite Particle Method (FPM), this paper presents the rigid-body contact simulation of 3D structures. The FPM models the space truss with finite particles. Following Newton's second law, every particle is in a permanent dynamic equilibrium. Fictitious motion procedures are developed in the particle internal force calculation to handle the geometric nonlinearity without iterative correction. Contact model and corresponding algorithm are developed based on the FPM. A numerical example is presented to demonstrate the capability of the FPM for analyzing rigid-body contact problems.
