Investigation of Stoneley Waves in Multilayered Plates

Abstract—Stoneley waves are interface waves that propagate at the interface between two solid media. In this study, the dispersion characteristics and wave structures of Stoneley waves in elastic multilayered plates are displayed and investigated. With a perspective of bulk wave, a reasonable assumption of the potential function forms of the expansion wave and shear wave in nth layer medium is ...

Attenuation of Lamb Waves in CFRP Plates

The paper presents the Lamb wave attenuation of Carbon Fiber Reinforced Plastic (CFRP) plates on the basis of an experimental transmitter-sensor scheme. We measured separately the S0 and A0 Lamb modes of CFRP plates with three different kind of laminate lay-ups; unidirectional [0]8s (and [90]8s), cross-ply [0, 90]4s, and quasi-isotropic [0,45,-45,90]2s. Several ultrasound transmitters were used...

Lamb Waves and Nearly-Longitudinal Waves in Thick Plates

We discuss waves created in relatively thick plates by edge excitation at frequency-thickness (fd) products that correspond, in principle, to multiple Lamb wave modes. For relatively low values of the fd product it is clear that Lamb wave modes will be generated, while at large values of the fd product we observe a bulk (longitudinal wave) in the solid, but influenced by reflections from the pl...

Transition from Lamb waves to longitudinal waves in plates

We use finite element simulations and experiments to examine the excitation of waves in a plate by normal forces applied to an edge. At low values of the frequency-plate thickness product, f·d, multiple Lamb wave modes are excited with different group velocities, but increasing f·d leads to the formation of a train of well-defined nearly-longitudinal pulses. We investigate the transition betwee...

Use of Lamb Waves to Monitor Plates: Experiments and Simulations

Lamb waves at ultrasonic frequencies travel with little attenuation in thin elastic plates, and we demonstrate their use in pulse-echo behavior to monitor plate integrity. We envision using a single PZT wafer-type transducer to generate waves and to receive reflections from distant flaw or boundary locations. However, Lamb waves generally have multiple modes, each of them highly dispersive, and...
