  • Galerkin finite element approximation of general linear second order hyperbolic equations 
    Basson, Madelein; Van Rensburg, N.F.J. (Taylor & Francis, 2013)
    In this article, we derive error estimates for the Galerkin approximation of a general linear second order hyperbolic equation. The results can be applied to a variety of cases, for example, vibrating systems of linked ...
  • Solvability of a model for the vibration of a beam with a damping tip body 
    Basson, Madelein; De Villiers, M.; Van Rensburg, N.F.J. (Hindawi Publishing, 2014-05)
    We consider a model for the vibration of a beamwith a damping tip body that appeared in a previous article. In this paper we derive a variational form for the motion of the beam and use it to prove that the model problem ...
  • Vibration of a Reissner-Mindlin-Timoshenko plate-beam system 
    Labuschagne, A.; Van Rensburg, N.F.J.; Van der Merwe, A.J. (Elsevier, 2009)
    In this paper, we consider a plate-beam system in which the Reissner-Mindlin plate model is combined with the Timoshenko beam model. Natural frequencies and vibration modes for the system are calculated using the finite ...
