Anisotropic Elastic Constants of a Fiber-Reinforced Boron-Aluminum Compositendomly distributed fibers, a full set of elastic constants can be predicted for this model. The random-distribution model agrees best with observation, especially for off-diagonal elastic constants. Considering all nine elastic constants, observation and theory differ on the average by six percent.

Evaluation of Sensitivity of Ultrasonic Detection of Delaminations in Graphite/Epoxy Laminates. Pulse echo and through transmission modes were used and A-scans, C-scans and frequency spectra were analyzed. It was found that the higher frequency (5MHz) compression transducer operated in the pulse-echo mode gave the best results in most cases. Shear wave transducers were found to be cumbersome to use and unsuitable for the cases studied.

Basic Wave Analysis of Acoustic Emissiontructural alteration in a solid material. Generally these structural alterations are a result of either internally or externally applied mechanical or thermal stress. Depending on the source mechanism, acoustic emission signals may occur with frequencies ranging from several hertz up to tens of mega
