Abstract: Motivated by the problem of vibrations due to joint clearance between components in complex mechanical systems, we study in this paper the motion of a beam between rigid obstacles. We assume that the material is elastic and the motion is planar. The contact is described with a non-penetration condition, which leads to a model of dynamics with unilateral constraints. We propose a family of fully discretised approximations and their convergence is established. Moreover we present some examples of implementation using either finite element or spline space discretisation.

Keywords: convergence; elastic beam; Signorini conditions; time discretisation; space discretisation; vibrations; unilateral constraints; beam motion; dynamic modelling; dynamics.
