Air-Coupled and Resonant Pulse-Echo Ultrasonic Technique
An ultrasonic, resonant, pulse-echo, and air-coupled nondestructive testing (NDT) technique is presented. It is intended for components, with regular geometries where it is possible to excite resonant modes, made of materials that have a high acoustic impedance (<i>Z</i>) and low attenua...
