Residual Stress Effects on Fatigue and Fracture Testing and Incorporation of Results Into Design
Author: J.O. Bunch, M.R. Mitchell | Size: 5 MB | Format:PDF | Publisher: A S T M International | Year: 2007 | pages: 157 | ISBN: 0803144725
This publication, Residual Stress Effects on Fatigue and Fracture Testing and Incorporation of Results into Design, contains papers presented at the Symposium on Residual Stress, which was held in Salt Lake City, UT on 19-20 May, 2004.
Eleven peer-reviewed papers, written by experts in their field, provide an understanding of residual stresses, fatigue crack growth, fatigue lifetime predictions, and their effect on structural integrity. Residual stresses can be present due to processing and manufacturing of materials and structures, so it is imperative to understand how and why they can influence the test data that we used in structural design methodologies. Residual stresses may also be intentionally engineered into structures in attempts to improve fatigue life, and it is equally important that designers understand how to account for these potential effects on fatigue life.

More Info:
The dilemma facing Cyprus—that of limited water supplies (both in terms of quantity and quality) in the face of steadily increasing water demand, coupled with a fragmented institutional structure of the water sector—is characteristic of most arid and semi-arid countries all over the world. Another common characteristic of Cyprus is that the water management administrative boundaries there do not coincide with the hydrological ones, while the ongoing political problem of the island creates significant administration problems.

This book covers the essential topics for a second-level course in strength of materials or mechanics of materials, with an emphasis on techniques that are useful for mechanical design. Design typically involves an initial conceptual stage during which many options are considered. At this stage, quick approximate analytical methods are crucial in determining which of the initial proposals are feasible. The ideal would be to get within 30% with a few lines of calculation. The designer also needs to develop experience as to the kinds of features in the geometry or the loading that are most likely to lead to critical conditions.
With this in mind, the author tries wherever possible to give a physical and even an intuitive interpretation to the problems under investigation. For example, students are encouraged to estimate the location of weak and strong bending axes and the resulting neutral axis of bending before performing calculations, and the author discusses ways of getting good accuracy with a simple one degree of freedom Rayleigh-Ritz approximation. Students are also encouraged to develop a feeling for structural deformation by performing simple experiments in their outside environment, such as estimating the radius to which an initially straight bar can be bent without producing permanent deformation, or convincing themselves of the dramatic difference between torsional and bending stiffness for a thin-walled open beam section by trying to bend and then twist a structural steel beam by hand-applied loads at one end.
In choosing dimensions for mechanical components, designers will expect to be guided by criteria of minimum weight, which with elementary calculations, generally leads to a thin-walled structure as an optimal solution. This consideration motivates the emphasis on thin-walled structures, but also demands that students be introduced to the limits imposed by structural instability. Emphasis is also placed on the effect of manufacturing errors on such highly-designed structures - for example, the effect of load misalignment on a beam with a large ratio between principal stiffness and the large magnification of initial alignment or loading errors in a strut below, but not too far below the buckling load.

Mixed finite element methods are a tool to solve complex engineering problems of different nature. This subject is treated in this volume from an engineering and mathematical point of view. Different applications are considered which depict the value of mixed formulations in engineering on one side. On the other side the mathematical background is provided including proofs of convergence and stability of these methods and adequate solvers for mixed problems are discussed. This broad spectrum yields an indepth treatment of mixed methods from different perspectives.
