Book Description
The primary objective of this program has been to develop simple laboratory-type tests to evaluate the toughness of high strength sheet alloys and their complex welded joints at cryogenic temperatures. The tests employed for evaluating the toughness of sheet materials included notiched tensile shear tests of individual resistance spot welds, and tensile tests of simple fusion welds. These tests were conducted at 78, -100, -320, and -423 F. These data, as well as data obtained from tensile tests of the base metal, percent martensite determinations, and metallographic examinations of fractured coupons, were correlated with low-cycle, highstress fatigue data obtained on complex welded joints at 78, -320, and -423 F. The most consistant index of toughness was found to be the notched/unnotched tensile ratio. The test data are presented in tabular and in graphical form to air metallurgical and design engineers in the selection of materials for structural applications at cryogenic temperatures. The test data were reduced by statistical methods and analzed. The results of the statistical analysis, which included means, standard deviations, and statistical values are presented and their importance discussed. A description of the test equipment and experimental procedures for tensile and fatigue testing at room and cryogenic temperatures is given. This report also includes conclusions, recommendations for future work, and references.

Book Description
In writing this monograph, the aim has been to consider the mechanical properties of the wide range of materials now available in such a way as to start with the fundamental nature of these properties and to follow the discussion through to the point at which the reader is able to comprehend the significance or otherwise of the large amounts of data now available in design manuals and other compilations. In short, it is hoped that this volume will be used as a companion to these data compilations and as an aid to their interpretation. In attempting to cover such a wide field, a large degree of selection has been necessary, as complete volumes have been written on topics which here have had to be covered in a few pages or less. It is inevitable that not everyone will agree with the choice made, especially if it is his own subject which has been discussed rather briefly, and the author accepts full res ponsibility for the selection made. The book is written at a level which should be easily followed by a university graduate in science or engineer ing, although, if his background has not included a course in materials science, some groundwork may be lacking.

Book Description
Fracture: An Advanced Treatise, Volume IV: Engineering Fracture Design presents the development and status of knowledge on sudden, catastrophic failure of structures due to unexpected brittle fracture of component materials. This book provides information pertinent to the engineering fracture design as well as the microscopic and macroscopic fundamentals of fracture. Organized into eight chapters, this volume begins with an overview of the evaluation of fracture tests. This text then presents an analysis of temperature effects on fracture. Other chapters consider the fracture and carrying capacity of long, slender columns and related topics. This book discusses as well the problems in connection with columns, beams, and plates, and experimental evidence to support theories proposed for describing the strength and stiffness of these elements. The final chapter presents an analysis of the problem of brittle fracture in weldments. This book is a valuable resource for engineers, students, and research workers in industrial organizations, education and research institutions, and various government agencies.

Book Description
Support from the National Science Foundation has made it possible for the tenth annual Cryogenic Engineering Conference, hosted by the University of Pennsylvania and capably directed by K. R. Atkins and his staff, to emphasize the major international advances in cryogenic engineering. This specific emphasis resulted in a final program of over one hundred papers and has made it necessary to publish the proceedings of the conference in two volumes. The first volume will be similar in nature to previous volumes in this series, while the second volume will feature the international aspect of the conference program. The latter volume, because of this distinction, will be entitled International Advances in Cryogenic Engineering. As in the past, the Cryogenic Engineering Conference Committee gratefully acknow ledges the assistance of all the dedicated workers in the cryogenic field who have contributed their time in reviewing the preliminary papers for the program and the final manuscripts for this volume. Since the list of participants in this thankless task numbers well over one hundred, any attempt to acknowledge their individual contributions in the limited space available would be practically impossible.

Book Description
This report is a bibliography of the work reported in the literature on the effects of low temperature on the properties of structural materials. Some of the newer areas of cryogenic technology such as superconducting machinery involve environments which may subject the components to temperature as low as 4 K. Exposure of structural materials to such low temperatures affects their properties. This bibliography contains 963 references published between 1950-1976, arranged in chronological/alphabetical order. Combined material/property indexes are provided. (Author).
