Band Structures Analysis of Elastic Waves Propagating along Thickness Direction in Periodically Laminated Piezoelectric Composites

Stress Dependence of Ultrasonic Velocity in Unidirectional Graphite/epoxy Composites for Longitudinal Waves Propagating along the Direction of Stress Introduction

One effect of nonlinear elasticity on elastic wave propagation is that the velocity of the elastic wave is a function of the applied stress on the material. This effect has been used to characterize the nonlinear elastic properties of numerous materials and is also important in attempts to nondestructively characterize residual and applied stress in materials. In addition, investigations have e...

A New Approach to Characterizing Acoustic Waves Propagating under a Periodically Electroded Array on Piezoelectric Substrate

The coupling problem between electrodes owing to acoustic wave propagation and electrostatic effect in a periodic metal grating on a piezoelectric substrate is theoretically studied. Harmonic admittance approach is used to obtain the complete acoustic wave spectrum, and mutual admittance is taken to describe wave propagation properties under the grating. Analytical expression for the contributi...

Dispersive Waves Propagating along a Surface Fracture

Significant work in the past few decades has lead to a well developed understanding of seismic wave propagation in fractured media. However, previous research has focused on fractures within rock as opposed to fractures at the surface of a rock. A theoretical and experimental study was performed to examine seismic wave propagation along a fracture at the surface, i.e., along the intersection of...
