These Proceedings, consisting of Parts A and B, contain the edited versions of most of the papers presented at the annual Review of Progress in Quantitative Nondestructive Evaluation held at Snowmass Village, Colorado, on July 31 to August 4, 1994. The Review was organized by the Center for NDE at Iowa State University, in cooperation with the Ames Laboratory of the US DOE, the Materials Directorate of the Wright Laboratory, Wright-Patterson Air Force Base, the American Society of Nondestructive Testing, the Department of Energy, the National Institute of Standards and Technology, the Federal Aviation Administration, the National Science Foundation Industry/University Cooperative Research Centers, and the Working Group in Quantitative NDE. This year's Review of Progress in QNDE was attended by approximately 450 participants from the U.S. and many foreign countries who presented over 360 papers. The meeting was divided into 36 sessions, with as many as four sessions running concurrently. The Review covered all phases of NDE research and development from fundamental investigations to engineering applications or inspection systems, and it included many important methods of inspection science from acoustics to x-rays. In the last eight to ten years, the Review has stabilized at about its current size, which most participants seem to agree is large enough to permit a full-scale overview of the latest developments, but still small enough to retain the collegial atmosphere which has marked the Review since its inception. 6 478 kr

It has been shown both experimentally {2} and theoretically {2,3} that surface skimming SH waves propagating along symmetry axes of the texture have velocities that differ in proportion to the magnitude of any stress that lies along one of the symmetry axes. Specifically, the stress is directly proportional to the relative velocity difference through the equation -,--V ik=---V. -=ki) ( I) cr. = 2G (-V ~ ik where cr. is the stress in the direction i, G is the shear modulus and Vik is the ~elocity of an SH wave propagating in the i direction and polarized in the k direction. This rather simple relationship is particularly useful because the constant of proportionality involves only the well known shear modulus and the velocity term can be measured directly by observing the transit time shift when a transmitter-receiver pair of SH wave transducers are rotated through 90 degrees on the surface of the part. Experimentally, Equation (I) was tested on the web of railroad rails which had been loaded by a 200,000 pound mechanical testing machine {I}. The method of exciting and detecting the necessary surface skimming SH waves used electromagnetic acoustic transducers (EMATs) that operated through a magnetostrictive mechanism at high magnetic fields {4}. Wave velocities parallel and perpendicular to the axis of the rail on the web differed by the amount predicted by Equation (I) to an absolute accuracy of 30 percent in the worst case. - E-bokPDF, Engelska, 2012

This volume (Parts A and B) contains the edited papers presented at the annual Review of Progress in Quan?itative Nondestructive Evalua tion held at the University of California (San Diego) in LaJo11a, August 3-8, 1986. The Review was organized and sponsored by the Center for NDE at Iowa State University and the Ames Laboratory, in cooperation with the Office of Basic Energy Sciences, USDOE, and the Materia1s Laboratory at Wright-Patterson Air Force Base. Approximately 400 attendees, a new record, representing various government agencies, industry, and universities participated in the technical presentations, poster sessions, and discussions. This Review, with its wide-ranging interchange of technical information, stands as one of the most compre hensive in the field of NDE research and engineering. In order to present the reader with a more usefu1 document, we have organized the symposium papers in these Proceedings by subject rather than by the order of presentation at the Review. Topical subject headings have been selected under which the 1arge majority of papers wou1d reasonably falI. Here, again, we have revised the format used in former years to accommodate an evolving focus of interest in the field. These categories cover a broad spectrum of research in NDE and encompass activities from fundamental work to early engineering applications. In the following paragraphs we offer a brief summary of the research presented in these Proceedings. - E-bokPDF, Engelska, 2012

In this volume (parts 1 and 2) are contained the edited papers presented at the annual Review of Progress in Quantitative NDE held at the University of California, San Diego, August 1-6, 1982. This Review, possibly the most comprehensive annual symposium emphasizing both ongoing research and applications in quantitative NDE, was sponsored by the Center for Advanced NDE at the Ames Laboratory of the U. S. Department of Energy in cooperation with the Materials Laboratory of the Air Force Wright Aeronautical Laboratories and the Defense Advanced Research Projects Agency. Over 300 attendees representing various government agencies and the industrial and university communities participated in the technical presentations, poster sessions, and discussions. The symposium benefited from the insight of two keynote speak ers, Dr. Harris Burte of the Materials Laboratory, AFWAL, and Mr. Ward Rummel of the Martin Marietta Corporation, who presented complementary messages. Dr. Burte pointed out the need to identify "windows" to serve as guides for focusing NDE research. The "window" concept may be thought of as an opportunity for the application of NDE technology to an important problem and, through this application, to identify knowledge gaps which must be filled by generic research. This concept simultaneously provides a mechanism for the solution of a direct ap plication problem and a set of strong guidelines for generic research directions.

The objective of this study was to increase the understanding of damage in composite materials with through-the-thickness reinforcements. As a first step it was necessary to develop new ultrasonic imaging technology to better assess internal damage of the composite. A useful ultrasonic imaging technique has been successfully developed to assess the internal damage of composite panels. The ultrasonic technique accurately determines the size of the internal damage. It was found that the ultrasonic imaging technique was better able to assess the damage in a composite panel with through-the-thickness reinforcements than by destructively sectioning the specimen and visual inspection under a microscope. Microscopic determination of crack location and lengths in a composite panel with through-the-thickness reinforcements was almost impossible. Five composite compression-after-impact panels were tested. The compression-after-impact strength of the panels with the through-the thickness reinforcements was almost twice that of the comparable panel without through-the-thickness reinforcement.

This volume (Parts A and B) contains the edited papers presented at the annual Review of Progress in Quantitative Nondestructive Evaluation held at Bowdoin College, Brunswick, ME on July 24-28, 1989. The Review was organized by the Center for Advanced NDE at the Ames Laboratory of the U. S. Department of Energy, in cooperation with the Office of Basic Energy Sciences, USDOE, and the Materials Laboratory at Wright-Patterson Air Force Base. The statistics for the 1989 Review of Progress in QNDE include a total of over 460 participants from the U. S. and nine foreign countries who presented some 325 papers. Over the years this conference has grown into one of the largest, most significant gatherings of NDE researchers and engineers in the world. The meeting was divided into 35 sessions, with as many as four sessions running concurrently, and covering all stages of NDE development from basic research investigations to early engineering applications and all methods of inspection science from ultrasonics to x-ray tomography. The Editors have organized the papers in the Proceedings according to topical subject headings, rather than in the original order of presentation. This rearrangement yields a more user-friendly reference work and follows a pattern now familiar to regular attendees of the Review. Some changes in the headings and their subcategories have been introduced to accommodate dynamic evolution of the field, as we observe it.
