Book Description
Fracture-toughness testing using principles of fracture mechanics has developed to the point where it can be used as a basis for selection of materials, for estimating limiting design stresses assuming the presence of small flaws, and for analyzing failures. Current methods of measuring plane-stress and plane-strain fracturetoughness parameters are presented in this report. The specimens include center-cracked, edge-cracked, single-edge-cracked, surface-cracked, and notched round bars, which are subjected to tensile loading, and notched bars for bend tests. The different types of specimens permit evaluating sheet, plate, bar stock, and forgings as well as material from failed structures. Application of fracture-toughness parameters to design of high-strength structures is reviewed for both static and fatigue loading. Consideration of the fracture-mechanics concepts in design should lead to fewer problems with brittle fracture in high-strength structures. (Author).

Book Description
This report is the third of a series which will periodically summarize the status of the various contracts involved in the Department of Defense Refractory Metals Sheet Rolling Program. Under this program, selected candidate materials are being carried through one or more of the following consecutive phases: Phase I, development of a sheet-production practice; Phase II, establishment of minimum design data; and Phase III, evaluation of sheetfabrication characteristics. To the present time, 13 contracts have been funded or planned in support of the Phase I, II, and III activities. This report summarizes the status of each of these individual contracts as of November 1, 1964. The first section describes the overall program of the Department of Defense Refractory Metals Sheet Rolling Program. Following, in the order of their discussions, are sections dealing with fabricable molybdenum alloys, unalloyed tungsten, columbium alloys, and tantalum alloys. (Author).

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.
