Download or read book Nondestructive Evaluation of Adhesive Bonds Using 20 MHz and 25 kHz Ultrasonic Frequencies on Metal and Polymer Assemblies written by Gilbert B. Chapman II and published by Author House. This book was released on 2014-07-17 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Demands for improvements in aerospace and automotive energy-efficiency, performance, corrosion resistance, body stiffness and style have increased the use of adhesive bonds to help meet those demands, by providing joining technology that accommodates a wider variety of materials and design options. However, the history of adhesive bond performance clearly indicates the need for a robust method of assuring the existence of the required consistent level of adhesive bond integrity in every bonded region. The Quality Assurance of Adhesive Bonds by Ultrasonic Nondestructive Testing technology put forth in this book meets that need by describing two new, complementary ultrasonic techniques for the evaluation of these bonds, and thus provide improvements over previous methods. The development of a 20 MHz pulse-echo method for nondestructive evaluation of adhesive bonds will accomplish the assessment of bond joints with adhesive as thin as 0.1 mm. This new method advances the state of the art by providing a high-resolution, phase-sensitive procedure that identifies the bond state at each interface of the adhesive with the substrate(s), by the acquisition and analysis of acoustic echoes reflected from interfaces between layers with large acoustic impedance mismatch. Because interface echo amplitudes are marginal when the acoustic impedance of the substrate is close to that of the adhesive, a 25 kHz Lamb wave technique was developed to be employed in such cases, albeit with reduced resolution. Modeling the ultrasonic echoes and Lamb-wave signals was accomplished using mathematical expressions developed from the physics of acoustic transmission, attenuation and reflection in layered media. The models were validated by experimental results from a variety of bond joint materials, geometries and conditions, thereby confirming the validity of the methodology used for extracting interpretations from the phase-sensitive indications, as well as identifying the range and limits of applications. Results from the application of both methodologies to laboratory specimens and to samples from production operations are reported herein, and show that bond-joint integrity can be evaluated effectively over the range of materials and geometries addressed.

Download or read book Nondestructive Characterization of Materials IV written by J.F. Bussière and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a great deal of interest in extending nondestructive technologies beyond the location and identification of cracks and voids. Specifically there is growing interest in the application of nondestructive evaluation (NOEl to the measurement of physical and mechanical properties of materials. The measurement of materials properties is often referred to as materials characterization; thus nondestructive techniques applied to characterization become nondestructive characterization (NDCl. There are a number of meetings, proceedings and journals focused upon nondestructive technologies and the detection and identification of cracks and voids. However, the series of symposia, of which these proceedings represent the fourth, are the only meetings uniquely focused upon nondestructive characterization. Moreover, these symposia are especially concerned with stimulating communication between the materials, mechanical and manufacturing engineer and the NDE technology oriented engineer and scientist. These symposia recognize that it is the welding of these areas of expertise that is necessary for practical development and application of NDC technology to measurements of components for in service life time and sensor technology for intelligent processing of materials. These proceedings are from the fourth international symposia and are edited by c.o. Ruud, J. F. Bussiere and R.E. Green, Jr. . The dates, places, etc of the symposia held to date area as follows: Symposia on Nondestructive Methods for TITLE: Material Property Determination DATES: April 6-8, 1983 PLACE: Hershey, PA, USA CHAIRPERSONS: C.O.

Download or read book Exploratory Development of Nondestructive Testing Techniques for Diffusion bonded Interfaces written by George Martin and published by . This book was released on 1969 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report covers exploratory development of nondestructive testing techniques for solid-state diffusion-bonded parts. A literature survey describes the current inspection practices employed on diffusion-bonded laminates and the nature of the interface and bond properties. Test specimens of titanium, columbium, and TD-nickel were prepared for evaluating various test methods. The specimens provided a range of thicknesses and varying degree of bond quality as determined by mechanical property tests. In addition, a number of diffusion-bonded specimens were supplied by the Air Force. Conventional ultrasonic techniques and recently developed selective interface inspection techniques clearly indicate bond conditions where these vary from a no-bond condition to substandard bonds. A number of methods show potential correlation between a quantitative expression of bond quality such as shear or tensile strength. These methods include longitudinal and shear wave velocity, ultrasonic attenuation, and vibration analysis. (Author).

This book was released on 2012-10-17 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: This STAR on asphalt materials presents the achievements of RILEM TC 206 ATB, acquired over many years of interlaboratory tests and international knowledge exchange. It covers experimental aspects of bituminous binder fatigue testing; the background on compaction methods and imaging techniques for characterizing asphalt mixtures including validation of a new imaging software; it focuses on experimental questions and analysis tools regarding mechanical wheel tracking tests, comparing results from different labs and using finite element techniques. Furthermore, long-term rutting prediction and evaluation for an Austrian road are discussed, followed by an extensive analysis and test program on interlayer bond testing of three different test sections which were specifically constructed for this purpose. Finally, the key issue of manufacturing reclaimed hot mix asphalt in the laboratory is studied and recommendations for laboratory ageing of bituminous mixtures are given.
Download or read book Fusion Bonding of Polymer Composites written by C. Ageorges and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fusion bonding is one of the three methods available for joining composite and dissimilar materials. While the other two, mechanical fastening and adhesion bonding, have been the subject of wide coverage both in textbooks and monographs, fusion bonding is covered here substantially for the first time. Fusion bonding offers a number of advantages over traditional joining techniques and it is anticipated that its use will increase dramatically in the future because of the rise in the use of thermoplastic matrix composites and the growing necessity for recyclability of engineering assemblies. Fusion Bonding of Polymer Composites provides an in-depth understanding of the physical mechanisms involved in the fusion bonding process, covering such topics as: - heat transfer in fusion bonding; - modelling thermal degradation; - consolidation mechanisms; - crystallisation kinetics; - processing-microstructure-property relationship; - full-scale fusion bonding; - fusion bonding of thermosetting composite/thermoplastic composite and metal/thermoplastic joints. The book focuses on one practical case study using the resistance welding process. This example exposes the reader to the development of processing windows for a novel manufacturing process including the use of experimental test programmes and modelling strategies.

This book was released on 2013-12-01 with total page 2101 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
