Abstract: Abstract This chapter presents several spectral element models for damaged waveguides. Models are developed for horizontal through-width single and multiple cracks (or delaminations), vertical through-width cracks (fiber breakages) and surface breaking cracks in 1D waveguides and vertical through-width cracks in 2D waveguides are addressed. Wave scattering due to these damage types are investigated with particular focus on composite structures. Examples shown in this chapter use both spectral element formulations previously presented, namely the FSFEM and WSFEM.
