... Abstract With radial and axial displacement of the arterial wall being considered, the problem on the pulse wave propagation in an initially-tensioned orthotropic artery is formulated and solved by using a free wave propagation approach, identifying the Young wave and the Lamb wave in an artery...

... Abstract The stress state of engineering structures is the key information for the reliability evaluation. However, conventional ultrasonic method is not suitable for local stress measurement. The dispersion characteristics of Lamb wave acoustoelasticity show that higher-order Lamb waves near...

... Abstract A Multistage Elliptical Parametric (MEP) method is developed in this research for damage size evaluation in anisotropic composite laminates. The Lamb waves are actuated and sensed using piezoelectric (lead zirconate titanate, PZT) transducers arranged as a network of square cells...

... plate using a PZT transducer network and Lamb waves is investigated. The thin disc PZT transducers surface mounted at the test plate are used as actuators to transmit the windowed sinewave bursts and sensors to receive the ultrasonic Lamb waves. The symmetrical S 0 mode and antisymmetrical A 0 mode...

... transmission/reception, processing, and interpretation. The EUSR methodology is developed as an extension of our previous work on the Lamb wave propagation NDE. Based on the study of the Lamb wave characteristic, the excitation signal is optimized to obtain good signal to noise ratio. Lamb wave speed-frequency...
