This text is for readers who want an introductory overview on the
mechanical and material factors of fracture in design analysis, material
and failure prevention. Both fundamental and practical concepts of
fracture are described in terms of stress analysis and the mechanical behavior
materials. The metallurgical aspects of deformation and fracture in
metals are also discussed. This book can serve as a desktop reference book, or a
self-study book, for engineering students and practicing engineers with
some, or without, prior training in solid mechanics and/or mechanical
metallurgy. The focus is on how machine (or structural) parts fail, why
one piece fails in a certain way and another piece fails differently; and
engineering tools for analyzing and, ultimately, preventing failure.
Metals occupy the main part of the book, but nonmetallic materials such as
ceramics, plastics, and fiber reinforced polymer matrix composites are
also included. The first two chapters of this book can be considered as the
fundamentals of stress analysis and mechanical behavior of materials.
Chapter 1 serves as a crash course (or a refresh course) in strength of
that prepares the reader with the basic analytical tools for the rest of
the book. Topics include: fracture mechanics, fatigue, and failures associated
with high-temperature creep, stress-corrosion, corrosion-fatigue, and
hydrogen-embrittlement. Numerous examples are given through out this book
to illustrate the elastic and plastic behavior of materials at a stress
raiser, and how the static, fatigue, and residual strengths of a machine part
have been affected by it.
