Summary Table of Contents Author Biography

Appropriate for all courses covering strength and elasticity in the context of aeronautical, civil, or mechanical engineering disciplines.Systematic, comprehensive, and practical, this classic exploration of real-world stress analysis has been thoroughly updated to reflect the latest methods and issues. It provides carefully balanced coverage of material mechanics, theory of elasticity methods, and computer-oriented numerical methods, all supported with a broad range of fully worked illustrative examples, many taken directly from actual enginee... MOREring practice. Coverage includes: strain and stress-strain relationships; two-dimensional problems in elasticity; material failure criteria; bending of beams; torsion of prismatic bars; axisymmetrically loaded members; beams on elastic foundations; energy methods; elastic stability; plastic behavior of materials; plates and shells; and more. Additions to the Fourth Edition include enhanced coverage of failure criteria; fracture mechanics; compound cylinders; numerical methods; energy and variational methods; buckling of stepped columns; and common shell types. The book also provides an extensive set of sample problems, as well as tables covering software for principle stresses and area properties; beam deflection, material properties, and conversion factors.

This systematic exploration of real-world stress analysis has been completely revised and updated to reflect state-of-the-art methods and applications now in use throughout the fields of aeronautical, civil, and mechanical engineering and engineering mechanics. Distinguished by its exceptional visual interpretations of the solutions, it offers an in-depth coverage of the subjects for students and practicing engineers. The authors carefully balance comprehensive treatments of solid mechanics, elasticity, and computer-oriented numerical methods. In addition, a wide range of fully worked illustrative examples and an extensive problem setsmany taken directly from engineering practicehave been incorporated. Key additions to the Fourth Edition of this highly acclaimed textbook are materials dealing with failure theories, fracture mechanics, compound cylinders, numerical approaches, energy and variational methods, buckling of stepped columns, common shell types, and more. Contents include stress, strain and stress-strain relations, problems in elasticity, static and dynamic failure criteria, bending of beams and torsion of bars, finite difference and finite element methods, axisymmetrically loaded members, beams on elastic foundations, energy methods, elastic stability, plastic behavior of materials, stresses in plates and shells, and selected references to expose readers to the latest information in the field.
