Available in PDF, EPUB and Kindle. Book excerpt: The influence of maximum stress, stress range, and sequence of load application on the rate and mechanism of fatigue crack propagation in 2024-T3 aluminum alloy was studied by means of electron fractography. The macroscopic growth rates were determined on center-notched crack grwoth panels and the fracture surfaces were examined by electron fractography. An empirical equation relating relative microscopic growth rates at a given crack length to maximum loads and load amplitudes was obtained. It was also found that the advance of a fatigue crack front takes place only during the loading part of a cycle and that in the pseudorandom load case the sequence of load application can markedly influence crack growth rate on any one cycle.

Available in PDF, EPUB and Kindle. Book excerpt: The influence of maximum stress, stress range, and sequence of load application on the rate and mechanism of fatigue crack propagation in 2024-T3 aluminum alloy was studied by means of electron fractography. Variable-amplitude loading programs were designed to provide tests under the following conditions: (1) constant maximum stress with three different levels of stress range, (2) constant stress range with three and four levels of maximum stress, (3) pseudo-random load application achieved by random distribution of the load spectra defined in Items 1 and 2, and (4) uniform maximum stress with peak overloads and underloads. The macroscopic growth rates were determined on center-notched crack growth panels, and the fracture surfaces were examined by electron fractography. The analysis of the influence of program loads on the rate and mechanism of fatigue crack growth was accomplished by: 1. Comparing plots of crack length versus measured rates of crack propagation for the different programs. The measured rates were also compared with rates calculated by a computer program. 2. Relating the count and spacing of the fatigue striations observed on the fracture surfaces with the applied load program.

Book Synopsis Handbook of Fatigue Crack Propagation in Metallic Structures by : A. Carpinteri
Download or read book Handbook of Fatigue Crack Propagation in Metallic Structures written by A. Carpinteri and published by Newnes. This book was released on 2012-12-02 with total page 834 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this Handbook is to provide a review of the knowledge and experiences in the field of fatigue fracture mechanics. It is well-known that engineering structures can fail due to cyclic loading. For instance, a cyclically time-varying loading reduces the structure strength and can provoke a fatigue failure consisting of three stages: (a) crack initiation (b) crack propagation and (c) catastrophic failure. Since last century many scientists have tried to understand the reasons for the above-mentioned failures and how to prevent them. This Handbook contains valuable contributions from leading experts within the international scientific community and covers many of the important problems associated with the fatigue phenomena in civil, mechanical and nuclear engineering.

Book Synopsis Mechanical Vibration and Shock Analysis, Fatigue Damage by : Christian Lalanne
Download or read book Mechanical Vibration and Shock Analysis, Fatigue Damage written by Christian Lalanne and published by John Wiley & Sons. This book was released on 2013-03-04 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanical Vibration and Shock Analysis, Second Edition Volume 4: Fatigue Damage Fatigue damage in a system with one degree of freedom is one of the two criteria applied when comparing the severity of vibratory environments. The same criterion is also employed for a specification representing the effects produced by the set of vibrations imposed in a real-world environment. In this volume, which is devoted to the calculation of fatigue damage, the author explores the various hypotheses and models used to describe the behavior of material suffering fatigue and the laws of fatigue accumulation. He also considers the methods of counting response peaks, which are used to establish a histogram when it is impossible to use the probability density of the peaks obtained with a Gaussian signal. The expressions for mean damage and its standard deviation are established and other hypotheses are tested. The Mechanical Vibration and Shock Analysis five-volume series has been written with both the professional engineer and the academic in mind. Christian Lalanne explores every aspect of vibration and shock, two fundamental and extremely significant areas of mechanical engineering, from both a theoretical and practical point of view. The five volumes cover all the necessary issues in this area of mechanical engineering. The theoretical analyses are placed in the context of both the real world and the laboratory, which is essential for the development of specifications.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Research on the Strength and Fracture of Materials: Volume 2As—The Physical Metallurgy of Fracture contains the proceedings of the Fourth International Conference on Fracture, held at the University of Waterloo, Canada, in June 1977. The papers review the state of the art with respect to the physical metallurgy of fracture in a wide range of materials such as metals, alloys, and structural steels. This volume is comprised of 85 chapters and opens by discussing the effect of grain size on the fracture of steel, aluminum alloys, and other materials. The influence of Mn additions on the fracture behavior of an Al-Mg-Si alloy is also considered, along with crack propagation in austenitic sheets. The next sections focus on the effect of phase transformation on the tensile fracture of austenitic stainless steel; atomistic simulation of the ductile/brittle transition; the effect of microstructure on fracture of a high toughness titanium alloy; and the effect of metallurgy on stress corrosion cracking and hydrogen embrittlement of ultra high strength steels. The remaining chapters are devoted to creep in materials such as Cr-Mo-V steels and titanium alloys. This monograph will be a useful resource for metallurgists, materials scientists, and structural and mechanical engineers.
