Abstract

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 are presented. The force-deformation equation contains a damping term to reflect dissipation in the contact area. The procedure is applied to show interaction and deformation processes as well as realistic animations.
