The subjects covered are applicable to a wide variety of structures and machines including automobiles, aerospace vehicles, bridges, tractors, bioimplants, and nuclear pressure vessels. The key prerequisite for efficient usage of the download free Metal Fatigue in Engineering Ralph I. Stephens 2nd edition book in pdf format  is knowledge of the mechanics of materials and materials science. The focus of this second edition, as with the first edition, is on applied engineering design with the intent to attain safe, reliable, and economical products. Adequate background information is provided on the different fatigue design methods to enable readers to judge the validity of the recommended models and procedures.

Metal Fatigue in Engineering Ralph I. Stephens 2nd edition pdf

Topics of interest primarily to researchers, yet not applied to actual fatigue design, have been omitted. The methods presented have been, and are, used successfully in fatigue design and life predictions/estimations. Twenty years have passed since the publication of the first edition. This is due to the untimely death of Professor Fuchs in 1989 when an effort had begun to write the second edition. In the spring of 1998, we decided to begin again with two new authors. Wiley Intercedence was in complete agreement with this decision since the first edition of download free Metal Fatigue in Engineering Ralph I. Stephens 2nd edition book in pdf format was very successful and was still producing sales after nearly 20 years of usage.

The first edition of download free Metal Fatigue in Engineering Ralph I. Stephens 2nd edition book in pdf format had even been translated into Chinese. The second edition is approximately 50 percent larger than the first edition due to extensive additional and updated text, figures, example problems, homework problems, chapter summaries, dos and don’ts in design, and references. A solutions manual for the second edition is also available to faculty using the book in a course.

New topics on fatigue in the second edition of download free Metal Fatigue in Engineering Ralph I. Stephens 2nd edition book in pdf format include computer-aided engineering and digital prototyping, enhanced discussion of micro/macro mechanisms and factors influencing fatigue behavior, small crack growth, elastic-plastic fracture mechanics, improved crack closure modeling., enhanced presentation of notch strain analysis that includes strain energy density or Glinka’s rule, critical plane approaches, and mixed-mode fatigue crack growth for multiaxial fatigue, expanded coverage of environmental effects, BS 7608 fatigue design code for weldments, and a new chapter on statistical aspects of fatigue, along with the expansion of the material property tables in the Appendix.

Four analytical methods of fatigue design and fatigue life prediction estimations for metals are covered: nominal stress (S-N), local strain (e-N), fatigue crack growth (daldN-AK), and a two-stage method involving e-N for nucleation of small cracks and da/dN-AK for continued crack growth until fracture. These four methods have been incorporated into many commercials, government, and in-house computer programs that have been used successfully in many complex fatigue design situations. These can involve notches, residual stresses, small and kong cracks, variable amplitude loading, multiaxial states of stress, and environmental conditions. The four analytical methods of download free Metal Fatigue in Engineering Ralph I. Stephens 2nd edition book in pdf format complement the need for verification testing under simulated and real-life conditions and form the basis of digital prototyping and computer-aided engineering for product durability.

Chapter Content of This Mechanical eBooks

Chapter 1 of download free Metal Fatigue in Engineering Ralph I. Stephens 2nd edition book in pdf format explains different mechanical failure modes and includes a historical overview of fatigue, including biographical sketches showing that the development of fatigue knowledge is a human endeavor. Chapter 2 introduces general fatigue design philosophies and procedures such as safe-life, fail-safe, and damage-tolerant design, synthesis, analysis, testing, digital prototyping, and inspection. Chapter 3 describes macroscopic and microscopic aspects of fatigue behavior and explains the mechanisms associated with fatigue crack nucleation and growth. The term “crack initiation” is not used, consistent with recent ASTM recommendations.

Chapter 4 of download free Metal Fatigue in Engineering Ralph I. Stephens 2nd edition book in pdf format involves fatigue testing, ASTM and ISO fatigue test standards for metals, and nominal stress-life (S-N) behavior for unnotched constant amplitude loading. Chapter 5 describes monotonic and cyclic stress-strain deformation behavior and strain life (E-N) fatigue behavior and properties for unnotched constant amplitude loading. Chapter 6 introduces LEFM concepts and their application to fatigue crack growth (daldN-AK) under constant amplitude loading. This includes crack closure, small and long cracks, and crack tip plasticity considerations.

Chapter 7  of download free Metal Fatigue in Engineering Ralph I. Stephens 2nd edition book in pdf format discusses the importance of stress concentrations and incorporates their effects into fatigue design using all four fatigue design methods. section 8 considers residual stresses with their production, relaxation, measurement, beneficial or detrimental effects, and residual and applied stress intensity factors for use in fatigue crack growth.

Chapter 9 to end student requirement to do

this section ( 9 ) of download free Metal Fatigue in Engineering Ralph I. Stephens 2nd edition book in pdf format  discusses cumulative damage and cycle counting and extends all four fatigue design methods developed in Chapters 4 through 7 to variable amplitude loading. Multiaxial fatigue including proportional and nonproportional loading, equivalent stresses and strains, critical plane approaches, and mixed-mode crack growth is covered in Chapter 10. Environmental effects including corrosion, fretting, low and high temperatures, and neutron irradiation are covered in Chapter 11.

Chapter 12 of download free Metal Fatigue in Engineering Ralph I. Stephens 2nd edition book in pdf format  covers the four fatigue design methods applied to fatigue of weldments, including the usage of British Standard BS 7608. Chapter 13 considers fatigue data scatter and probabilistic aspects of fatigue design. In the Appendix, five tables on fatigue and fracture toughness properties for selected engineering materials have the text and the problems. Example problems are included to better show the applicability of the concepts to engineering design situations. Unsolved problems are included at the end of each chapter, and in some cases, more than one answer, or a range of answers, is reasonable because of different ways of modeling, methods of solution, material properties are chosen, and the inherently empirical and non-exact nature of fatigue and fatigue design.

The 166 problems often require the reader to indicate the significance of a solution and to comment on the assumptions made. Each chapter of download free Metal Fatigue in Engineering Ralph I. Stephens 2nd edition book in pdf format has significant references (424 total, an increase of about 40 percent) and figures (183 total), a Summary section, and a “Dos and Don’ts in Design” section. SI units are used with American units where appropriate. Most figures and tables have dual units.
