A one-dimensional model for variations of longitudinal wave velocity under different thermal conditions
Ultrasonic testing is a versatile and important nondestructive testing method. In many industrial applications, ultrasonic testing is carried out at relatively high temperatures. Since the ultrasonic w...
متن کاملLongitudinal iso-phase condition and needle pulses.
We study the properties of pulsed solutions to the scalar and vector wave equations composed of plane-waves with equal longitudinal spatial frequency. This condition guarantees that, at all times, the field profile is invariant in the longitudinal direction. Particular emphasis is placed on solutions with rotational symmetry. For these solutions, the wave concentrates strongly near the axis at ...
متن کاملInductive coupling for wireless Lamb wave and longitudinal wave transducers
Piezoelectric transducers have been widely used for the generation and detection of ultrasonic waves for structural health monitoring. Recently, we proposed the use of inductive coupling in order to implement wireless coupling to a Lamb wave transducer. In that transducer the ultrasonic waves were generated by a piezoelectric wafer attached to the surface of a plate. These transducers are effec...
متن کاملPropagation Dynamics of Airy Water-Wave Pulses.
We observe the propagation dynamics of surface gravity water waves, having an Airy function envelope, in both the linear and the nonlinear regimes. In the linear regime, the shape of the envelope is preserved while propagating in an 18-m water tank, despite the inherent dispersion of the wave packet. The Airy wave function can propagate at a velocity that is slower (or faster if the Airy envelo...
متن کاملDemonstrating the Importance of Multi-wave Assessment of Peer Victimization
" " " ii" " " " iii" ABSTRACT Christopher S. Sheppard: Demonstrating the Importance of Multi-wave Assessment of Peer Victimization (Under the direction of Mitchell J. Prinstein) The current study assessed the extent to which chronic victimization is a unique type of peer victimization. This was examined using stability analyses, trajectory analyses, and comparisons of victimization and adjustme...
