	%X –In this paper the damage in clamped-free, clampedclamped and free-free beam are analyzed considering samples 
without and with structural modifications. The damage location is 
investigated by the use of the bispectrum and wavelet analysis. The 
mathematical models are obtained using 2D elasticity theory and the 
Finite Element Method (FEM). The numerical and experimental data 
are approximated using the Particle Swarm Optimizer (PSO) method 
and this way is possible to adjust the localization and the severity of 
the damage. The experimental data are obtained through 
accelerometers placed along the sample. The system is excited using 
impact hammer.
