Download or read book CORROSION RESISTANCE AND DURABILITY OF FASTENERS IN AIRCRAFT STRUCTURES written by and published by . This book was released on 1967 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: A corrosion and fatigue evaluation was made to determine whether the rounding of countersunk holes and/or fastener heads would improve the corrosion behavior at the fastener locations or affect the fatigue strength of 7075-T6 aluminum alloy joints assembled with cadmium plated steel countersunk head screws. Test assemblies were prepared with and without corrosion barrier materials, including a MIL-S-8802 polysulfide sealant, in the finishing system. Rounded configurations did not significantly improve corrosion behavior but did improve the fatigue strength of the specimens. The greatest improvement in fatigue properties occurred with a combination of rounded fastener heads and rounded countersunk holes. Of the various corrosion barrier materials tested, only the polysulfide sealant afforded good corrosion protection when used with a paint system overcoat. However, the use of the sealant more than negated the beneficial effect of the rounded configurations on fatigue strength. The use of the sealant lowered the fatigue strength of the control specimens with standard fastener heads and standard countersunk holes by approximately 6%. This loss is counterbalanced by the improvement in corrosion behavior afforded by the sealant to fastener areas.

This book was released on 2007 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annotation Eleven peer-reviewed papers provide the latest information on the structural integrity of fasteners, including the effect s of environmental and stress corrosion cracking. For Sections cover: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. Design/Environmental Effects?two papers examined 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. 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 s the resistance of high strength fine thread bolts for multiple preload conditions. Design Consideration?focuses on the comprehensive nonlinear 3D finite element model to simulate a displacement controlled for riveted structure; state-of-the-art fatigue crack growth analysis techniques which 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.

Download or read book DeGarmo s Materials and Processes in Manufacturing written by J. T. Black and published by John Wiley & Sons. This book was released on 2020-07-21 with total page 902 pages. Available in PDF, EPUB and Kindle. Book excerpt: Guiding engineering and technology students for over five decades, DeGarmo's Materials and Processes in Manufacturing provides a comprehensive introduction to manufacturing materials, systems, and processes. Coverage of materials focuses on properties and behavior, favoring a practical approach over complex mathematics; analytical equations and mathematical models are only presented when they strengthen comprehension and provide clarity. Material production processes are examined in the context of practical application to promote efficient understanding of basic principles, and broad coverage of manufacturing processes illustrates the mechanisms of each while exploring their respective advantages and limitations. Aiming for both accessibility and completeness, this text offers introductory students a comprehensive guide to material behavior and selection, measurement and inspection, machining, fabrication, molding, fastening, and other important processes using plastics, ceramics, composites, and ferrous and nonferrous metals and alloys. This extensive overview of the field gives students a solid foundation for advanced study in any area of engineering, manufacturing, and technology.
