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.
