Metal Fatigue in Engineering

By Ralph I. Stephens

Book Overview

Applied Optimal Design Mechanical and Structural Systems Edward J. Haug & Jasbir S. Arora This computer-aided design text presents and illustrates techniques for optimizing the design of a wide variety of mechanical and structural systems through the use of nonlinear programming and optimal control theory. A state space method is adopted that incorporates the system model as an integral part of the design formulations. Step-by-step numerical algorithms are given for each method of optimal design. Basic properties of the equations of mechanics are used to carry out design sensitivity analysis and optimization, with numerical efficiency and generality that is in most cases an order of magnitude faster in digital computation than applications using standard nonlinear programming methods. 1979 Optimum Design of Mechanical Elements, 2nd Ed. Ray C. Johnson The two basic optimization techniques, the method of optimal design (MOD) and automated optimal design (AOD), discussed in this valuable work can be applied to the optimal design of mechanical elements commonly found in machinery, mechanisms, mechanical assemblages, products, and structures. The many illustrative examples used to explicate these techniques include such topics as tensile bars, torsion bars, shafts in combined loading, helical and spur gears, helical springs, and hydrostatic journal bearings. The author covers curve fitting, equation simplification, material properties, and failure theories, as well as the effects of manufacturing errors on product performance and the need for a factor of safety in design work. 1980 Globally Optimal Design Douglass J. Wilde Here are new analytic optimization procedures effective where numerical methods either take too long or do not provide correct answers. This book uses mathematics sparingly, proving only results generated by examples. It defines simple design methods guaranteed to give the global, rather than any local, optimum through computations easy enough to be done on a manual calculator. The author confronts realistic situations: determining critical constraints; dealing with negative contributions; handling power function; tackling logarithmic and exponential nonlinearities; coping with standard sizes and indivisible components; and resolving conflicting objectives and logical restrictions. Special mathematical structures are exposed and used to solve design problems. 1978

Excellent Textbook

This is an excellent textbook. It covers all of the basic aspects of metal fatigue and some topics that are left out of elementary texts; for instance, environmental effects, the fatigue of weldments and the statistical aspects of fatigue. The book begins with an excellent historical review of the subject, which contains capsule biographies of some of the most important contributors to the field. Both the stress and strain life approaches are covered, as are, crack nucleation and growth, the fatigue in notches, and variable amplitude loading. While the book is not primarily a source for fatigue data, it does contain some specific data. This book is not as detailed or comprehensive as Suresh's Fatigue of Materials, but it is, in my opinion, a much better choice as a textbook for use in a course (advanced undergraduate or graduate) on metal fatigue or as part of a course on the mechanical properties of materials. In fact, in my opinion it is currently the best choice as a textbook on the subject of fatigue.

Excellent Text on Fatigue

This is by far the best text on the topic of fatigue I've ever read. You cannot go wrong with this book. Not only do they do a fantastic job on the technical side, they also provide a beautifully prepared historical background to the topic that puts everything in perspective. Upon finishing the book the reader understands just how dynamic this topic is and has a thirst to know more. The author(s) do a superb job of explaining all aspects of fatigue including a chapter on LEFM. Each chapter has a "Do's and Don'ts of Design" section which is very informative. Each time I read one of those sections I would come across things that I had learned through many year's of experience (the hard way, if you will). These confirmations helped to solidify my opinion of the book. I should point out, the Appendix in the text on material properties is reason enough to purchase the book. The contents are very difficult to find elsewhere. If you have an interest in the topic or your career requires knowledge on the subject, this book is a must have.

Review for: Metal Fatigue in Engineering

Stephens tries to capture as much information in this book as needed for the practicing fatigue engineer. It's a great book to have on the shelf.

One of the main references for modern Fatigue Analysis

Very good book. It tackles all the main aspects of modern Fatigue Analysis. The atentive reader, following the text with a paper and pencil besdies, will extract valuable ideas for procedures. I am looking forward for books written in the same style.

Great overview with engineering data!

If there is a single book on *just* metal fatigue for your shelf, this is it. The treatment of material is rigorous without being too terse or long-winded. There's an enjoyable amount of real-world experience mixed in with the text: bits of highly relevant distilled information. Plus, there is data in the appendix that is difficult to find elsewhere (aluminum, etc).
