Book Synopsis Mixed Mode Fatigue Crack Growth Behavior in a High-Strength Steel by : RE. Link
Download or read book Mixed Mode Fatigue Crack Growth Behavior in a High-Strength Steel written by RE. Link and published by . This book was released on 1993 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the currently available methods for predicting fatigue crack growth in structures do not consider effects due to mixed-mode loading. This is partly due to the limited information available concerning the fatigue crack growth under mixed mode loading. Previous investigations of mixed mode effects on fatigue crack growth have shown that under combined opening and in-plane shear loading, the cracks turn abruptly so that the in-plane shear mode is eliminated [1-3]. Very little data are generated before the crack curvature eliminates the mixed mode loading. The changing orientation of the crack during the test makes analysis of the problem difficult and may cloud the intrinsic fatigue crack growth rate behavior under mixed mode loading. Situations can exist in engineering structures in which cracks may grow in a self-similar manner even under the influence of mixed mode loading. Examples of such situations are radial cracks in bearing races [4] and transverse cracks in rotating shafts under shear and bending loads. The cracks may not change orientation because the in-plane shear component is fully reversed. It is necessary to understand the effects of mixed mode loading on fatigue crack growth in order to properly predict the behavior of these components.

Book Synopsis Fatigue Crack Growth Behavior of a High-Strength Steel by : Maurice F. Amateau
Download or read book Fatigue Crack Growth Behavior of a High-Strength Steel written by Maurice F. Amateau and published by . This book was released on 1971 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue crack growth behavior of high-strength Ladish D6AC steel was examined under various conditions of frequency, environment, temperature, stress ratio, and stress intensity history. Materials with fracture toughness ranging from 50 to 100 ksi/sq. in., but with the same yield strength of 220 ksi, were examined. Variations in fracture thoughness do not have a strong effect on crack growth rate at stress intensity levels within the log-linear portion of the crack growth curves. Different environments, such as dry air, laboratory air, and distilled water, were found to produce different fatigue crack growth behavior at 1 Hz but not at 10 Hz loading frequency. The lowest crack growth rate occurred in dry air, while the aggressive environment of distilled water affected the crack growth rate more severly at lower stress intensity levels. The effects of temperature over the range from -40 to 175F are a uniform shift of the growth curve to low crack growth rates and a lowering of the stress intensity level for the onset of rapid fatigue crack propagation. Suppression of crack growth rate following high prior stress cycles is the most significant effect of stress history. This effect cannot be explained in terms of the relative plastic zone sizes alone. (Author).
Book Synopsis Fatigue Crack Growth Behavior of Four High Strength Steels in Two Humid Environments by : C. E. Neu
Download or read book Fatigue Crack Growth Behavior of Four High Strength Steels in Two Humid Environments written by C. E. Neu and published by . This book was released on 1971 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue crack growth rates (da/dN) as a function of applied stress intensity amplitude (delta K) were determined for four high strength steels (HP 9-4-.45, 18% Ni marage 250, D6Ac, AISI 4340) in air at 10 percent and at 80 percent relative humidities (R.H.). All four steels demonstrated sensitivity to high humidity with crack growth rates in 80 percent R.H. air being one and one-half to two times as high as in 10 percent R.H. air. Overall crack growth rates of three steels, HP 9-4-.45, 18% Ni marage 250, and D6Ac, were similar, while rates for AISI 4340 were uniformly higher than those of the other three steels. (Author).

Book excerpt: This book contains the fully peer-reviewed papers presented at the Third Engineering Foundation Conference on Small Fatigue Cracks, held under the chairmanship of K.S. Ravichandran and Y. Murakami during December 6-11, 1998, at the Turtle Bay Hilton, Oahu, Hawaii.

Book Synopsis The Virtual Crack Closure Technique: History, Approach and Applications by : Ronald Krueger
Download or read book The Virtual Crack Closure Technique: History, Approach and Applications written by Ronald Krueger and published by . This book was released on 2002 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: An overview of the virtual crack closure technique is presented. The approach used is discussed, the history summarized, and insight into its applications provided. Equations for two-dimensional quadrilateral elements with linear and quadratic shape functions are given. Formula for applying the technique in conjuction with three-dimensional solid elements as well as plate/shell elements are also provided. Necessary modifications for the use of the method with geometrically nonlinear finite element analysis and corrections required for elements at the crack tip with different lengths and widths are discussed. The problems associated with cracks or delaminations propagating between different materials are mentioned briefly, as well as a strategy to minimize these problems. Due to an increased interest in using a fracture mechanics based approach to assess the damage tolerance of composite structures in the design phase and during certification, the engineering problems selected as examples and given as references focus on the application of the technique to components made of composite materials.
Book Synopsis Mathematical and Computational Analyses of Cracking Formation by : Yoichi Sumi
Download or read book Mathematical and Computational Analyses of Cracking Formation written by Yoichi Sumi and published by Springer. This book was released on 2014-06-11 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about the pattern formation and the evolution of crack propagation in engineering materials and structures, bridging mathematical analyses of cracks based on singular integral equations, to computational simulation of engineering design. The first two parts of this book focus on elasticity and fracture and provide the basis for discussions on fracture morphology and its numerical simulation, which may lead to a simulation-based fracture control in engineering structures. Several design concepts are discussed for the prevention of fatigue and fracture in engineering structures, including safe-life design, fail-safe design, damage tolerant design. After starting with basic elasticity and fracture theories in parts one and two, this book focuses on the fracture morphology that develops due to the propagation of brittle cracks or fatigue cracks. In part three, the mathematical analysis of a curved crack is precisely described, based on the perturbation method. The stability theory of interactive cracks propagating in brittle solids may help readers to understand the formation of a fractal-like cracking patterns in brittle solids, while the stability theory of crack paths helps to identify the straight versus sharply curved or sometimes wavy crack paths observed in brittle solids. In part four, the numerical simulation method of a system of multiple cracks is introduced by means of the finite element method, which may be used for the better implementation of fracture control in engineering structures. This book is part of a series on “Mathematics for Industry” and will appeal to structural engineers seeking to understand the basic backgrounds of analyses, but also to mathematicians with an interest in how such mathematical solutions are evaluated in industrial applications.

Available in PDF, EPUB and Kindle. Book excerpt: The importance of the nanoscale effects has been recognized in materials research for over fifty years, but it is only recently that advanced characterization and fabrication methods are enabling scientists to build structures atom-by-atom or molecule-by molecule. The understanding and control of the nanostructure has been, to a large extent, made possible by new atomistic analysis and characterization methods pioneered by transmission electron microscopy. Nano and Microstructural Design of Advanced Materials focuses on the effective use of such advanced analysis and characterization techniques in the design of materials. Teaches effective use of advanced analysis and characterization methods at an atomistic level Contains many supporting examples of materials in which such design concepts have been successfully applied
