Abstract:

Crack detection and impact source identification in materials is a renowned problem found in variety of commercial and military applications like beams, bridges, turbines, pavements, armor plates, vehicle body plates, bones, teeth, and so on. This long-standing interest in development of CDISI is evident from variety of methods proposed in the literature. Ultrasonic guided waves are used for the crack detection. The crack detection is done by measuring lamb wave signals using the dual PZT transducer. Wireless inductively-coupled transducers are used for the crack detection. The wave velocities of concrete are measured by the portable transient elastic wave system to track the health of concrete. Automation for different crack detection and impact source identification methods is lately carried out in the literature using soft computing and VLSI techniques.
