ASTM International Publishes STP 1487, Structural Integrity of Fasteners Including the Effects of Environmental and Stress Corrosion Cracking

Press release date: June 28, 2007

STP 1487, Structural Integrity of Fasteners Including the Effects of Environmental and Stress Corrosion Cracking: 3rd Volume, is now available from ASTM International. STP 1487 contains eleven peer-reviewed papers that provide the latest information on the structural integrity of fasteners, including the effects of environmental and stress corrosion cracking. Four sections cover: o Fatigue and Crack Growth Experimental Techniques-Three papers cover the development of a fastener structural element test for certifying navy fasteners material; experimental crack growth behavior for aerospace application; and influence of cold rolling threads before and after heat treatment on the fatigue resistance of high strength coarse thread bolts for multiple preload conditions. o Design/Environmental Effects-Two papers examine the relationship between the tightening speed with friction and clamped-load; and the optimum thread rolling process that improves SCC resistance to improve quality of design. o Fatigue and Crack Growth Analytical Techniques-Three papers describe current analytical techniques for fatigue and crack growth evaluations of fasteners; a numerical crack growth model using the finite element analysis generated stress field; and the resistance of high strength, fine thread bolts for multiple preload conditions. o Design Consideration-Focuses on the comprehensive, nonlinear 3-D finite element model to simulate a displacement controlled for riveted structure; state-of-the-art fatigue crack growth analysis techniques that are used in various industries to damage tolerance evaluation of structures; and the material stress state within the thread of the bolt; and on each parameter affecting the structural integrity of a bolted joint. Pir M. Toor, Bettis Atomic Power Laboratory, and Joseph Barron, Northrop Grumman, served as the editors for this volume. Copies of STP 1487, Structural Integrity of Fasteners Including the Effects of Environmental and Stress Corrosion Cracking: 3rd Volume (150 pages, soft cover, 6" x 9"; ISBN: 978-0-8031-3413-3; stock # STP1487) are available for $66 from ASTM Customer Service (phone: 610/832-9585; fax: 610/832-9555; service@astm.org) or online at www.astm.org.
