  2. Lamb waves - Wikipedia

    en.wikipedia.org/wiki/Lamb_waves

    In acoustic emission testing, the challenge is to recognize the multiple Lamb wave components in the received waveform and to interpret them in terms of source motion. This contrasts with the situation in ultrasonic testing, where the first challenge is to generate a single, well-controlled Lamb wave mode at a single frequency.

  3. Rayleigh wave - Wikipedia

    en.wikipedia.org/wiki/Rayleigh_wave

    However, the particle motion of surface waves is larger than that of body waves, so the surface waves tend to cause more damage. In the case of Rayleigh waves, the motion is of a rolling nature, similar to an ocean surface wave. The intensity of Rayleigh wave shaking at a particular location is dependent on several factors: Rayleigh wave direction

  4. Variation potential - Wikipedia

    en.wikipedia.org/wiki/Variation_potential

    A variation potential (VP) (also called slow wave potential) is a hydraulically propagating electrical signal occurring exclusively in plant cells. It is one of three propagating signals in plants, the other two being action potential (AP) and wound potential (WP) (also unique to plants). [ 1 ]

  5. Ultrasonic testing - Wikipedia

    en.wikipedia.org/wiki/Ultrasonic_testing

    Principle of ultrasonic testing. LEFT: A probe sends a sound wave into a test material. There are two indications, one from the initial pulse of the probe, and the second due to the back wall echo. RIGHT: A defect creates the third indication and simultaneously reduces the amplitude of the back wall indication.

  6. Beam tracing - Wikipedia

    en.wikipedia.org/wiki/Beam_tracing

    Beam tracing is an algorithm to simulate wave propagation. It was developed in the context of computer graphics to render 3D scenes, but it has been also used in other similar areas such as acoustics and electromagnetism simulations. Beam tracing is a derivative of the ray tracing algorithm that replaces rays, which have no thickness, with beams.
