Laser-based ultrasonic sensing generally requires the probe to have a fixed focal length or
to be contact. On the other hand, such a requirement is not essential in laser-based …

An ultrasonic propagation imaging (UPI) system consisted of a Q-switched Nd-YAG pulsed
laser and a galvanometer laser mirror scanner was developed. The system which requires …

Pressure vessels are widely used in industrial fields, and some of them are safety-critical
components in the system—for example, those which contain flammable or explosive …

Nondestructive eddy current methods were used to evaluate the electrical conductivity
behavior of silicon-carbide particulate (SiCp) reinforced aluminum (Al) metal-matrix …

Previous work investigated using guided waves for monitoring creep deformation during
accelerated life testing. The basic objective was to relate observed changes in the time-of …

Laser-based ultrasonic sensing requires the probe with fixed fecal length, but this
requirement is not essential in laser-based ultrasonic generation. Based on this fact, we …

An integral transform method is employed to predict the normal surface displacement
resulting from the elastic waves initiated by a variety of line sources embedded within plates …

Performing in-situ measurements of specimens in research reactors is challenging because
of the environmental conditions. In this paper, two approaches were investigated for …

An ultrasonic method for the nondestructive evaluation (NDE) of composite laminates using
mode-converted plate waves is explained analytically and physically, and the validity of the …
