The definitive guide to stress concentration, newly revised and updated

Stress concentration factors are used in the design of mechanical or engineering structures and machinery and have a tremendous impact on design of virtually every product or structure subject to environmental or use–related stress from nuclear equipment, deep–sea vehicles, and aircraft to space vehicles, underground tunnels, and turbines. But the sheer volume of stress concentration data is now so large that analysts and designers may have difficulty integrating this information efficiently into design applications.

Now in its third edition, Peterson′s Stress Concentration Factors establishes and maintains a system of data classification for all of the applications of stress and strain analysis and expedites their synthesis into CAD applications. This new edition of the book has been substantially revised and completely updated and presents stress concentration factors both graphically and with formulas. Structures and shapes of interest can be easily accessed via an illustrated table of contents that permits identification based on the geometry and loading of the location of a factor.

This updated Third Edition features:

  • Completely updated and revised coverage of the most recent stress concentration factors, including geometric discontinuities in tubes and countersunk holes in plates

  • The how–to′s of optimizing a shape to circumvent stress concentration problems and to achieve a well–balanced design of structures and machines that will result in reduced costs, lighter products, and improved performance

  • New guidelines for the likely stress decay away from the point of the stress concentration for various holes and notches

  • New methods for analyzing and calculating the stress concentration factors based on the length of elements and on the location of loading on components

More comprehensive and up–to–date than previous editions, Peterson′s Stress Concentration Factors is an essential addition to the professional libraries of engineers and designers working in the automotive, aerospace, and nuclear industries; for civil and mechanical engineers; and for students and researchers in these fields.
