Abstract: The dispersion relationships of a system comprising a circular bar imbedded in a solid medium having a lower acoustic impedance than the bar have been predicted. A generic study of such systems ...

Abstract: There is currently a need to improve the nondestructive testing techniques that are used to inspect grouted steel reinforcing tendons, anchors, and rock bolts for corrosion and fracture. A method of inspection using guided ...

Abstract: The reflection of the L(0, 2), axially symmetric guided elastic wave from notches in pipes is examined, using laboratory experiments and finite element simulations. The results show that the ...

Abstract: A study of the reflection of mode-converted guided waves from notches in pipes has been carried out. Measurements were made on a 76-mm bore diameter (nominal 3-inch), 5.5-mm wall thickness ...
