Book excerpt: The point of the memorandum is to emphasize the danger in accepting engineering data at face value. The definition of units used in the measurement of engineering parameters related to solid materials is discussed. A major portion of the memorandum is concerned with micromechanical strength parameters in solids such as yield strength, elastic limit, and proportional limit. Variation of elastic 'constants' in ordinary engineering materials under various conditions is discussed. A final section of the memorandum discusses variation of the thermal expansion coefficient in materials. (Author).

This book was released on 1964 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: A brief study of delayed fracture in a seam-welded titanium panel is summarized in this memorandum. Examination of the fracture surface with electron microscopy showed that the material cleaved, failing in a brittle manner. Although the nature of the embrittlement was not clearly defined, titanium hydride phase was suspected as a prime contributor to failure. Even though the hydrogen content of the titanium was only 65 ppm, hydride embrittlement was thought to have occurred from precipitation of hydride platelets on crystal planes oriented normal to welding stresses. Other work, briefly discussed in the memorandum, has confirmed that hydride platelets in titanium can be oriented by stress and that tensile ductility of Zircaloy (which behaves similarly with respect to hydrogen, to titanium) depends upon hydride orientation. Stress-relief annealing of welded titanium structures is recommended wherever possible to minimize embrittlement by stress-oriented hydrides. (Author).

Download or read book Continued Observations on the Distribution of Stress in the Vicinity of a Crack in the Center of a Plate written by L. R. Jackson and published by . This book was released on 1964 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: This memorandum supplements and augments information presented in DMIC Memorandum 178 (AD-422 463). In the present report, Neuber's stress equations are rewritten entirely in rectangular coordinates. In addition, numerical results have been extended to include the stress distribution around an indefinitely sharp crack. It is also shown that the stress function used in a British work for an indefinitely sharp crack yielded identical numerical results, even though the stress function was of a different type than that employed by Neuber. The Von Mises relation was chosen to delineate the area around a crack in which plastic flow is occurring. The numerical tables in this memorandum give values for the function of plane stress as well as one possible interpretation of plane strain. Values of the hydrostatic stress variant are also given for both plane stress and plane strain. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Experimental programs concerned with the oxidation of titanium and its alloys are reviewed and results compared with those predicted by theory. Wagner-Hauffe theory is used as the primary basis for comparison, and its inconsistencies are pointed out. Fifteen binary alloy systems involving titanium are covered, as well as a few ternary and commercial alloys. A short section discusses the effects of oxygen or nitrogen contamination on the mechanical properties of titanium and its alloys. (Author).

Book excerpt: Porosity in fusion welds in titanium has been encountered to some extent in all programs using this joining method. While measures to control cleanliness and to employ good welding techniques have successfully reduced the occurrence of porosity, specific indentification of the various causes of porosity is still lacking. Some factors suspected of causing porosity in titanium welds are hydrogen, cleanliness of joint area, contamination in filler wire, and welding procedures and techniques.

Download or read book Handbook of Optomechanical Engineering written by Anees Ahmad and published by CRC Press. This book was released on 1996-12-20 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Good optical design is not in itself adequate for optimum performance of optical systems. The mechanical design of the optics and associated support structures is every bit as important as the optics themselves. Optomechanical engineering plays an increasingly important role in the success of new laser systems, space telescopes and instruments, biomedical and optical communication equipment, imaging entertainment systems, and more. This is the first handbook on the subject of optomechanical engineering, a subject that has become very important in the area of optics during the last decade. Covering all major aspects of optomechanical engineering - from conceptual design to fabrication and integration of complex optical systems - this handbook is comprehensive. The practical information within is ideal for optical and optomechanical engineers and scientists involved in the design, development and integration of modern optical systems for commercial, space, and military applications. Charts, tables, figures, and photos augment this already impressive handbook. The text consists of ten chapters, each authored by a world-renowned expert. This unique collaboration makes the Handbook a comprehensive source of cutting edge information and research in the important field of optomechanical engineering. Some of the current research trends that are covered include:

Download or read book Stability of Microstructure in Metallic Systems written by J. W. Martin and published by Cambridge University Press. This book was released on 1997-03-06 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of this textbook, popular amongst students and faculty alike, investigates the various causes of thermodynamic instability in metallic microstructures. Materials theoretically well designed for a particular application may prove inefficient or even useless unless stable under normal working conditions. The authors examine current experimental and theoretical understanding of the kinetics behind structural change in metals. The entire text has been updated in this new edition, and a completely new chapter on highly metastable alloys has been added. The degree to which kinetic stability of the material outweighs its thermodynamic instability is very important, and dictates the useful working life of the material. If the structure is initially produced to an optimum, such changes will degrade the properties of the material. This comprehensive and well-illustrated text, accompanied by ample references, will allow final year undergraduates, graduate students and research workers to investigate in detail the stability of microstructure in metallic systems.
