title = "Ultrasonic guided wave mode selection and tuning in composites using a piezoelectric phased array",
abstract = "Ultrasonic guided wave based methods are attracting significant interest due to their tremendous potential for structural health monitoring (SHM). Penetration power and sensitivity improvement are the major challenges in guided wave based technologies for detection and quantification of structural damage. This paper presents a physically based understanding of ultrasonic guided wave propagation and excitation behaviors in composite structures, which can be used as an essential building block for future physically based SHM system design. A semi-analytical finite element method is used to study wave propagation characteristics and the normal mode expansion technique is used to study the wave excitation characteristics. A powerful and flexible guided wave mode tuning technique is then studied through the utilization of a synthetic phased array.",
