Traditional methods of determining phase and group velocities are often inadequate for many thick‐section materials that exhibit greater than 30 dB, frequency‐dependent propagation losses across the passband of the transducer. This article descri

A measurement method for determining phase and group velocities in many thick-section materials that exhibit greater than 30 dB, frequency-dependent propagation losses across the passband of a transducer is presented. The method is mechanized as a pu

The authors describe an experimental air-coupled, ultrasonic measurement system that can be used to study the propagation of megahertz signals in wooden plates ranging in thickness from 3 to 25 mm. They also report experimental measurements of the am

A proposed ISO standard specifies tolerances on longitudinal-wave velocity measurements made on IIW-type calibration blocks. These specifications conflict with current ASTM standards for velocity measurements. We evaluate the tolerances of the propos

In materials characterization, a material’s transfer function is calculated from experimental data. Sometimes, the transfer function of the measurement device, such as an ultrasonic transducer, must be known for this calculation. One of the common

Previous work has compared the relative performance of various wide-band ultrasonic transducers used as receivers [1]. Studies have also been made comparing the merits of various optical sensors [2] and evaluating their applicability to acoustic emis

Ultrasonic inspection is a standard method to assess the integrity of large-diameter oil pipelines. However, similar methods applied to natural-gas pipelines present a considerably greater challenge; gas is a poor coupling agent for the probing ultra

It has been established that the risk of damage to paintings on wood (“panel paintings”) increases with the presence of cracks, delaminations, and their associated stress concentrations. Such flaws can originate and increase in size as a result o
