Abstract :
We developed a finite element method (FEM) for examining small transverse vibrations of a damaged beam. The damage is modelled as an elastic joint and standard Hermite piecewise cubics were adapted to use as basis functions in the FEM. This method can be used in situations where the characteristic equation approach is not viable.
