Download or read book A Computer Controlled Automated Test System for Fatigue and Fracture Testing written by RK. Nanstad and published by . This book was released on 1990 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computer-controlled system consisting of a servohydraulic test machine, an in-house designed test controller, and a desktop computer has been developed for performing automated fracture toughness and fatigue crack growth testing both in the laboratory and in hot cells for remote testing of irradiated specimens. Both unloading compliance and dc-potential drop can be used to monitor crack growth. The test controller includes a dc-current supply programmer, a function generator for driving the servohydraulic test machine to required test outputs, five measurement channels (each consisting of low-pass filter, track/hold amplifier, and 16-bit analog-to-digital converter), and digital logic for various control and data multiplexing functions. The test controller connects to the computer via a 16-bit wide photoisolated bidirectional bus. The computer, a Hewlett-Packard Series 200/300, inputs specimen and test parameters from the operator, configures the test controller, stores test data from the test controller in memory, does preliminary analysis during the test, and records sensor calibrations, specimen and test parameters, and test data on flexible diskette for later recall and analysis with measured initial and final crack length information. During the test, the operator can change test parameters as necessary.

This book was released on 1990 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: An automated fatigue and fracture laboratory was recently set up at the National Aeronautical Laboratory. Six servohydraulic load frames are connected to a single multi-user, time-sharing computer system, through dedicated microprocessor-based interfaces. The host computer system includes resources for post processing of test data, output of test results and their storage and retrieval.

Download or read book A Fracture Mechanics Test Automation System for a Basic Research Laboratory written by GA. Hartman and published by . This book was released on 1990 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Successful selection of a material test automation strategy, hardware, and software depends on careful evaluation of the requirements of the target laboratory. Some of the criteria include the type of testing (single event, continuous), the laboratory mission (basic research, production testing, quality assurance), the operator's level of understanding of the testing and automation system, the available laboratory space, and the financial constraints. This paper discusses automation strategy, hardware, and software that have been used to automate a basic research laboratory performing fatigue crack propagation testing under a variety of test conditions including elevated temperatures.

Download or read book Fatigue and Fracture Testing Using a Multitasking Minicomputer Workstation written by RD. Evans and published by . This book was released on 1990 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: An automated fatigue and fracture toughness testing control system is described that is based on a Sun 3/180 workstation computer running under the UNIX operating system. Real-time difficulties associated with UNIX have been overcome with a unique combination of software and modified data acquisition hardware that results in a system not requiring conventional analog-to-digital (A/D) and digital-to-analog (D/A) device drivers. The control system software subroutines utilize the multitasking feature of UNIX to permit plotting, computations, and A/D operations to run simultaneously with D/A output. Inputs to the system are primarily through a mouse-driven, menu-based window methodology. The program currently contains four versatile cyclic loading sequences for fatigue crack growth and LEFM and EPFM fracture evaluations that can be applied to five commonly utilized specimen geometries. The software and hardware system has been demonstrated and validated for numerous tests using various materials and specimen types.

Download or read book Fatigue of Materials and Structures written by Claude Bathias and published by John Wiley & Sons. This book was released on 2013-03-04 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design of mechanical structures with improved and predictable durability cannot be achieved without a thorough understanding of the mechanisms of fatigue damage and more specifically the relationships between the microstructure of materials and their fatigue properties. Written by leading experts in the field, this book (which is complementary to Fatigue of Materials and Structures: Application to Damage and Design, also edited by Claude Bathias and André Pineau), provides an authoritative, comprehensive and unified treatment of the mechanics and micromechanisms of fatigue in metals, polymers and composites. Each chapter is devoted to one of the major classes of materials or to different types of fatigue damage, thereby providing overall coverage of the field. The book deals with crack initiation, crack growth, low-cycle fatigue, gigacycle fatigue, shorts cracks, fatigue micromechanisms and the local approach to fatigue damage, corrosion fatigue, environmental effects and variable amplitude loadings, and will be an important and much used reference for students, practicing engineers and researchers studying fracture and fatigue in numerous areas of mechanical, structural, civil, design, nuclear, and aerospace engineering as well as materials science.
