This chapter brings together several representative case studies conducted by the authors. In these selected studies, major algorithms introduced in Chapter 6 are employed to identify structural damage of increasing complexity, ranging from identification of a notch in a simple structural alloy beam using a damage index (DI) to quantitative evaluation of delamination in composite panels using the artificial neural network (ANN) technique. Key issues addressed in the preceding chapters, including activation of Lamb waves, finite element method (FEM) simulation, mode selection, active sensor network, signal processing, data fusion and identification algorithms, are further elaborated in individual case studies.
