Li, Yan, "Application of ultrasonic guided waves to the characterization of texture in metal sheets of cubic and hexagonal crystallites " (1990 INFORMATION TO USERSThe most advanced technology has been used to photograph and reproduce this manuscript from the microfihn master. UMl films the text directly from the original or copy submitted. Thus, some thesis and dissertation copies are in typewriter face, while others may be from any type of computer printer.The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistt^ct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction.In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion.Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand corner and continuing from left to right in equal sections with small overlaps. Each original is also photographed in one exposure and is included in reduced form at the back of the book.

“…This dissertation concludes with a summary, a list of references cited, acknowledgements, and an appendix that describes a useful signal processing method to determine ultrasonic velocity or wave number information for the dispersive SQ waves. This method has been implemented in an ultrasonic texture/stress measurement system that has just been built at Iowa State University, and the method has been found to produce highly accurate results [41,42].…”

Ultrasonic techniques have recently been applied to the texture characterization in polycrystalline aggregates of hexagonal crystals. The basis of this application lies in the relations between the elastic constants Cy of the aggregates, which can be inferred from ultrasonic wave velocity measurements, and the orientation distribution coefficients. This communication presents such relations for aggregates which possess orthotropic material symmetry and hexagonal crystal symmetry for Voigt, Reuss, and Hill averaging methods in a unified and concise representation.
