WebContact-type ultrasonic test is commonly used in construction industry where gel-couplant is applied the the material being tested and the transducers to assure is wave propagation will travel through without any air gaps. However, is method has disadvantages, since outside preparation is considering prior to testing. Another method of experiment without the … Rayleigh waves are a type of surface acoustic wave that travel along the surface of solids. They can be produced in materials in many ways, such as by a localized impact or by piezo-electric transduction, and are frequently used in non-destructive testing for detecting defects. Rayleigh waves are part of the seismic waves that are produced on the Earth by earthquakes. When guided in layers they are referred to as Lamb waves, Rayleigh–Lamb waves, or generalized Rayleigh waves.
