With an eye on new technology and a concern for safety and durability in engineering design, this book covers the entire area of mechanical behavior of materials from a practical engineering viewpoint, providing a single-source introductory analysis with specific coverage on materials testing, yield criteria, stress-based fatigue, fracture mechanics, crack growth, strain-based fatigue, and creep. It is ideal for students who have completed elementary mechanics of materials and who need to study practical engineering methods for analyzing parts of machines, vehicles, and structures to determine if trial designs or existing parts are adequate enough to ensure the components' strength and durability. NEW-Significantly revises and expands coverage on fracture mechanics, stress-based fatigue, and creep. NEW-Adds two new appendices; one that reviews useful topics from elementary mechanics of materials, and one that considers statistical variation in materials properties. NEW-Materials Property Locator aids in quickly finding this information in tables throughout the book. NEW-Contains approximately 423 end-of-chapter Problems and Questions (37% new or substantially revised). Emphasizes the practical engineering methods of testing structural materials to obtain their properties and then predict their strength and life when they are made into parts of machines, vehicles, and structures.
