Signal Processing Techniqueshat indicate the state of the structure. This chapter addresses some of the important issues regarding signal processing of the measured signals, as it applies to the detection and characterization of damage.

Perturbation Methods for Damaged Structuresd be a horizontal crack (through width delamination) or through width vertical crack (fiber breaks). Modeling of some of these defects were addressed in the last chapter and the methods presented here represent another approach to the simplified modeling of these defects.

Bridging Scales Analysis of Wave Propagation in Heterogeneous Structures with Imperfectionsh is limited to the small region around the discontinuity. The co-existence of two scales in the model is handled through the application of proper bridging relations between the two scales, and the generation of interaction forces at the interfaces according to the .. This technique allows a coarse

Modeling of Actuators and Sensors for SHMy elements, and through their spatial arrangement is presented for the simple case of a linear, one-dimensional array. The basic principles are then applied to the case of a two-dimensional configuration which has the ability to generate beam steering through proper tuning of the excitation frequenc
