Download or read book Design of a Data Acquisition and Reduction System for Fatigue Testing written by Jerry Wayne Dalton and published by . This book was released on 1981 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: A data acquisition and reduction system has been created for aircraft materials fatigue testing. The system uses an HP-9835 Desktop Calculator, an HP-2240A Measurement and Control Processor and a Materials Testing System loading machine. Three different computer programs on the HP-9835 are used to analyze material properties, simulate inflight fatigue loading and compute fatigue damage at a stress concentration. The flight loads are selected from Mil Spec 8866 and applied in a random order. The fatigue damage at a stress concentration is calculated from the applied local stresses using Miner's Law. (Author).

Download or read book Fatigue Testing and Analysis written by Yung-Li Lee and published by Elsevier. This book was released on 2011-04-18 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue Testing and Analysis: Theory and Practice presents the latest, proven techniques for fatigue data acquisition, data analysis, and test planning and practice. More specifically, it covers the most comprehensive methods to capture the component load, to characterize the scatter of product fatigue resistance and loading, to perform the fatigue damage assessment of a product, and to develop an accelerated life test plan for reliability target demonstration. This book is most useful for test and design engineers in the ground vehicle industry. Fatigue Testing and Analysis introduces the methods to account for variability of loads and statistical fatigue properties that are useful for further probabilistic fatigue analysis. The text incorporates and demonstrates approaches that account for randomness of loading and materials, and covers the applications and demonstrations of both linear and double-linear damage rules. The reader will benefit from summaries of load transducer designs and data acquisition techniques, applications of both linear and non-linear damage rules and methods, and techniques to determine the statistical fatigue properties for the nominal stress-life and the local strain-life methods. Covers the useful techniques for component load measurement and data acquisition, fatigue properties determination, fatigue analysis, and accelerated life test criteria development, and, most importantly, test plans for reliability demonstrations Written from a practical point of view, based on the authors' industrial and academic experience in automotive engineering design Extensive practical examples are used to illustrate the main concepts in all chapters

Available in PDF, EPUB and Kindle. Book excerpt: The software for an aircraft fatigue monitoring data acquisition system was designed and implemented on a prototype instrument to evaluate the feasibility of employing such a system in the data collection process for the determination of fatigue effects in aircraft structures. The operating software and the associated hardware are described herein; options for actual implementation in light of rapid technological developments are hypothesized and discussed. Separate software packages provide for the data collection and retrieval, including the pre-processing of data to a form which is suitable for computation. Results of test cases are presented where the software is proved by comparison of output to controlled input signals.
Download or read book A Computerized Data Acquisition System for High Temperature Pressurized Water Fatigue Test Facility written by WH. Cullen and published by . This book was released on 1980 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The hardware and software of a data acquisition system for a high-temperature, high-pressure water fatigue crack growth facility is described in this article. This system monitors crack lengths of 15 specimens, together with water pressures, temperatures, and water chemistry data such as dissolved oxygen content, pH, and specific conductance. The measurement strategy is defined by the cyclic count: each of the specimens has its unique measurement targets and measurement interval. The computer constantly compares the instantaneous accumulated count with the count targets of the 15 specimens and enters a data acquisition subprogram when any count target is reached. The methods of data acquisition, data reduction, file management, input/output and system status modification are described.

Download or read book Full Scale Fatigue Testing of Components and Structures written by K. J. Marsh and published by Butterworth-Heinemann. This book was released on 2013-10-22 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: Full-scale Fatigue Testing of Components and Structures presents the approaches to the testing of full-scale components or structures. The book begins by examining the necessity or desirability of full-scale fatigue testing. Subsequent chapters are devoted to the discussion of fatigue testing done on aircraft structures, railway components, helicopter rotor heads, artillery gun structures, and bridge components. The role of full-scale fatigue testing on automotive components and systems, structural testing in nuclear engineering, and the use of a structural fatigue testing laboratory for other tests are covered as well. Engineers, materials scientists, and researchers in the field of fatigue testing will find the book very useful.
Download or read book A Data Acquisition and Control Program for Axial Torsional Fatigue Testing written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-08-09 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computer program was developed for data acquisition and control of axial-torsional fatigue experiments. The multitasked, interrupt-driven program was written in Pascal and Assembly. This program is capable of dual-channel control and six-channel data acquisition. It can be utilized to perform inphase and out-of-phase axial-torsional isothermal fatigue or deformation experiments. The program was successfully used to conduct inphase axial-torsional fatigue experiments on 304 stainless steel at room temperature and on Hastelloy X at 800 C. The details of the software and some of the results generated to date are presented. Kalluri, Sreeramesh and Bonacuse, Peter J.
