A guide to NDE of composite materials by acoustic wave propagation, including advanced ultrasound methods, for detailed identification and measurement of defects, and characterization of microstructure and properties. "The major objective is to present the basic concepts of wave propagation in anisotropic media, and to show how these concepts can be applied to the quantitative, nondestructive evaluation of composite media."

"Measuring material properties…is a relatively new application of ultrasonics. Dr. Kline points out those areas where more research is needed, and those areas where the method is not yet refined enough to give accurate results… provides a good theoretical background to the topic, and serves as a starting point for research into experimental methods."
