Polar Characteristics of the Group and Phase Velocities as Well as the Frequency Dependence of Lamb culations of the angular dependence of the phase and group velocities of bulk waves in the graphite/epoxy composite material. The advantage of the Lamb wave technique over bulk waves is the ability to measure the in-plane anisotropic properties of thin composite plates such as those used in actual aircraft applications.

Beam-Hardening Correction Methods for Polychromatic X-Ray CT Scanners used to Characterize Structura effort has gone into developing BH corrections for industrial materials such as ceramics. The purpose of this paper is to present a BH correction method that takes into account both the photon spectrum of the X-ray head and the properties of ceramic materials. Scattering contributions to image degradation will not be considered here.

In-Process Ultrasonic Nondestructive Evaluatione, temperature or pressure. And third, ultrasonic waves may be used on-line for inspection of part quality. Measurements of the process parameters and material properties make possible the control of process variables to achieve the required material properties..

Characterization of Isotropic Composites Containing Inclusions of Specified Shapes by use of Ultrasoand from this point of view, polymer composites offer excellent characteristics. This factor and others such as versatility, ease of fabrication and cost effectiveness are some of the reasons why composite plastics are rapidly gaining ground over the more usual engineering materials.

Origin of Flaws from Ceramic Processing parts. These parts are required to withstand a high design stress which infers that the critical flaw size be very small. The flaw size is usually outside the limits of NDE detection. Since all ceramic materials of importance are essentially brittle, one can estimate the flaw size from the linear elastic fracture mechanics,
