WebMulti-channel analysis of surface waves (MASW) software can be used to transform recorded Rayleigh waves (specific type of surface wave) generated using either an active … 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 … See more Rayleigh waves are a type of surface wave that travel near the surface of solids. Rayleigh waves include both longitudinal and transverse motions that decrease exponentially in amplitude as distance from the surface … See more Rayleigh waves are widely used for materials characterization, to discover the mechanical and structural properties of the object being tested – like the presence of cracking, and the related shear modulus. This is in common with other types of surface … See more Generation from earthquakes Because Rayleigh waves are surface waves, the amplitude of such waves generated by an … See more • Linear elasticity • Longitudinal wave • Love wave • P-wave • Phonon • S-wave See more Rayleigh waves propagating at high ultrasonic frequencies (10–1000 MHz) are used widely in different electronic devices. In addition to Rayleigh waves, some other types of surface acoustic waves (SAW), e.g. Love waves, are also used for this purpose.
