Non-contact feature detection using ultrasonic Lamb waves

Patent Sinha, Dipen N [Los Alamos, NM]

Apparatus and method for non-contact ultrasonic detection of features on or within the walls of hollow pipes are described. An air-coupled, high-power ultrasonic transducer for generating guided waves in the pipe wall, and a high-sensitivity, air-coupled transducer for detecting these waves, are disposed at a distance apart and at chosen angle with respect to the surface of the pipe, either inside of or outside of the pipe. Measurements may be made in reflection or transmission modes depending on the relative position of the transducers and the pipe. Data are taken by sweeping the frequency of the incident ultrasonic waves, usingmore » « less

ULTRASONIC LAMB-WAVE PROPAGATION MODELS FOR NONDESTRUCTIVE TESTING APPLICATIONS

Technical Report Fitch, C E

Studies were carried out on the ultrasound propagation in thin Zircaloy specimens. Basic Lamb wave propagation formulas are presented, and a technique was developed for separating Lamb waves irto longitudinal and shear wave components. Sound leakage from the end of Zircaloy plates vibrating in the Lamb wave domain was observed using the Schlieren image technique. The above effects are discussed relative to nondestructive testing of Zircaloy tubing. (D.L.C.)
ULTRASONIC TESTING WITH LAMB WAVES

Technical Report Worlton, D C

A method is described whereby many types of flaws lying close to the surface of a metal can be ultrasonically detected, regardless of the time duration of the interrogating pulses. Lamb waves are established in the metal between a flaw and the surface by an ultrasonic beam which impinges at the proper angle of incidence. A suitably positioned receiver transducer picks up the waves to reveal the flaw. In this method the usually troublesome surface echo is eliminated from the receiver by an acoustic barrier, making it well suited for routine and automatic testing.
