Lamb Waves in a Poroelastic Plate
Currently, bone mineral density (BMD) is the gold standard for in vivo assessment of frac23 ture risk of bones and is measured using X-ray absorptiometric techniques.1 However, only 24 70–80% of the variance of bone strength is accounted for by bone density. As the brittle25 ness of bone depends on more factors than bone density, biologists believe that quantitative 26 ultrasound techniques (QU...
متن کاملPropagation of ultrasonic Lamb waves in adhesively bonded lap joints
This paper considers the bonded joint as a multilayer structure that is analysed using the Transfer Matrix method. In this particular case three layers (two adherents and the adhesive) are considered. The study of this propagation problem may be developed from matrix formulations which describe elastic waves in layered media. This technique combines the theory of the dynamics of the continuum w...

متن کاملNumerical Simulation of Nonlinear Lamb Waves Used in a Thin Plate for Detecting Buried Micro-Cracks
Compared with conventional linear ultrasonic inspection methods, which are sensitive only to severe defects, nonlinear ultrasonic inspection methods are better for revealing micro-cracks in thin plates. However, most nonlinear ultrasonic inspection methods have only been experimentally investigated using bulk or Rayleigh waves. Numerical studies, especially numerical simulations of Lamb ultraso...
متن کاملPropagation of Thickness-Twist Waves in an Infinite Piezoelectric Plate
Thickness-twist waves in piezoelectric plates are widely used as the operating modes for acoustic wave resonators, filters, sensors, and other devices (Mindlin, 1965; Mindlin, 1967; Pearman, 1968; Bleustein, 1966; Bleustein, 1969; Yang et al., 2008a; Yang & Guo, 2006). Acoustic waves in these devices are driven by an alternating voltage applied to the electrodes deposited on the plates. Therefo...
