Download or read book Determination of Fracture Stress and Effective Crack Tip Radius from Toughness KIc and Yield Strength Y written by and published by . This book was released on 1993 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the last of several reports in which KIc toughness is not considered basic, but dependent on two metallurgically controllable parameters, the tensile nil-ductility fracture stress and an effective crack tip radius formed by straining at the sharp crack tip which is shown by examples not to be uniquely dependent on load as would the mathematical increase in radius of a rounded tip no matter how small, in a homogeneous material but also dependent metallurgically on micromechanical structure. The reports describe how to determine the fracture stress and the radius from KIc tests with the aid of a postulated fracture criterion characteristic of the material and a curve derived from the solution for the state of stress in the yielded region of a short elliptically shaped flat crack lying across the center of a plate under uniform tensile loading. Here a more exact solution by Colin E. Freese and Dennis M. Tracey supplants the approximate ones used previously and it is shown that dependent on tempering or test temperature, radius determinations remain unchanged to 20% larger although fracture stress determinations are 75% to 85% as large.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this major reference work is to provide a first point of entry to the literature for the researchers in any field relating to structural integrity in the form of a definitive research/reference tool which links the various sub-disciplines that comprise the whole of structural integrity. Special emphasis will be given to the interaction between mechanics and materials and structural integrity applications. Because of the interdisciplinary and applied nature of the work, it will be of interest to mechanical engineers and materials scientists from both academic and industrial backgrounds including bioengineering, interface engineering and nanotechnology. The scope of this work encompasses, but is not restricted to: fracture mechanics, fatigue, creep, materials, dynamics, environmental degradation, numerical methods, failure mechanisms and damage mechanics, interfacial fracture and nano-technology, structural analysis, surface behaviour and heart valves. The structures under consideration include: pressure vessels and piping, off-shore structures, gas installations and pipelines, chemical plants, aircraft, railways, bridges, plates and shells, electronic circuits, interfaces, nanotechnology, artificial organs, biomaterial prostheses, cast structures, mining... and more. Case studies will form an integral part of the work.

Available in PDF, EPUB and Kindle. Book excerpt: Fracture and Fracture Mechanics: Case Studies contains the proceedings of the Second National Conference on Fracture, held at the University of the Witwatersrand in Johannesburg, South Africa on November 26-27, 1984. This book presents case studies in fracture and fracture mechanics and highlights the problems associated with fracture, failure analysis, and safe design in industries as diverse as mining, power generation, transport, petrochemical, and manufacturing. This book has 29 chapters divided into five sections and opens with a discussion on the role of professional complacency in bridge failures. The first section is devoted to failure investigation and covers topics ranging from failure analysis of a hydraulic retarder piston to the use of scanning electron microscopy in investigating tungsten carbide-cobalt fractured components. The second section deals with slow crack growth and considers an approach to assessing structural integrity and fatigue failures in vibrating equipment. Failures arising from repair welding and incomplete heat treatment are described. The remaining chapters explore fitness for purpose evaluation of fractures; the environmental effects of fractures; and case studies of failure prevention in industries such as petrochemical, power generation, and transportation. This monograph will be of interest to structural engineers, metallurgists, and materials scientists and technologists.

Download or read book Modern Applied Fracture Mechanics written by Cameron Coates and published by CRC Press. This book was released on 2022-08-02 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern Applied Fracture Mechanics presents a practical, accessible guide to understanding and applying basic linear elastic fracture mechanics (LEFM) techniques to problems commonly seen in industry, including fatigue analysis, failure analysis, and damage tolerance. Including applications for several software programs, AFGROW, MATLAB®, ABAQUS, and a web-based FM calculator, the book discusses appropriate models, assumptions, and typical input/output parameters. It provides a framework that will enable readers to quickly learn and use fracture mechanics (FM) software packages and/or write their own code to solve unique or standard FM problems. The book covers the fundamental concepts needed to successfully execute routine applications or conduct experimental investigations. End-of-chapter problems are included, along with real-world examples to enhance student understanding. The textbook is appropriate for undergraduate students, preparing them for the industry, and for advanced studies in fracture mechanics at the graduate level. Industry professionals and researchers will find this book a valuable resource for understanding basic fracture mechanics principles and methods. Features include: Provides broad, accessible coverage of common fracture mechanics concepts and applications. Focuses on applications, real-world examples, and numerical methods in fracture analysis. Integrates and explains current end-user software coverage for fracture mechanics. Includes numerous sample problems, software examples, and end-of-chapter problems. Includes a Solutions Manual for adopting instructors.

Book excerpt: A comprehensive survey is presented of current methods of fracture toughness testing that are based on linear elastic fracture mechanics. General principles are discussed in relation to the basic two-dimensional crack stress field model and in relation to real three-dimensional specimens. The designs and necessary dimensions of specimens for mixed mode and opening mode (plane strain) crack toughness measurement are considered in detail. Methods of test instrumentation and procedure are described. Expressions for the calculation of crack toughness values are given for the common types of specimens.
