Lamb Waves in Acousto-ultrasonic Testing
... Acousto-ultrasonic testing differs from ultrasonic testing in that it was conceived as a means of assessing damage (and other material attributes) distributed over substantial areas, rather ...
Lamb Waves in Ultrasonic Testing
... The purpose of ultrasonic testing is usually to find and characterize individual flaws in the object being tested ... Traditionally, ultrasonic testing has been conducted with waves whose wavelength is very much shorter than the dimension of the part being inspected ... In this high-frequency-regime, the ultrasonic inspector uses waves that approximate to the infinite-medium longitudinal and shear wave modes, zig-zagging to and ...
Scaling And Root Planing - Physical Principles - How Does It Work?
... Surprisingly, the mechanism of action underlying the operation of ultrasonic scaler on microscopic scale is somewhat controversial ... Recent contributions claim that ultrasonic scalers generate acoustic cavitation in the medium surrounding the teeth ... can not occur in a dry environment, it comes out that the role of the liquid output of the ultrasonic scaler during its operation is far more essential than cooling and rinsing the presence of ...
