Force identification from dynamic responses of a bimaterial beam

  • James F. Doyle


The dynamic response due to impact of a two-dimensional bimaterial beam system is described in terms of a waveguide model involving two displacements and a rotation. Coupled with spectral analysis, this allows measured signals to characterize the waves propagating in the system; this in turn, is used to predict responses at any locations. In particular, the impacting force can be reconstructed. The results are demonstrated for an aluminum/expoxy system.
