O autorze

Anthony Bedford is Professor Emeritus of Aerospace Engineering and Engineering Mechanics at the University of Texas at Austin. He has been on the faculty since 1968. He also has industrial experience at Douglas Missiles and Space Systems Division, Sandia National Laboratories, and at TRW, where he worked on the Apollo program. His main professional activity has been education and research in engineering mechanics. He is coauthor of Engineering Mechanics: Statics and Dynamics (with Wallace T. Fowler) and Introduction to Elastic Wave Propagation (with Douglas S. Drumheller).

Kenneth Liechti is Professor of Aerospace Engineering and Engineering Mechanics at the University of Texas at Austin and holds the Zarrow Centennial Professorship in Engineering. He received a B.Sc. in Aeronautical Engineering at Glasgow University and M. S. and Ph.D. degrees in Aeronautics at the California Institute of Technology. He gained industrial experience at General Dynamics Fort Worth Division prior to joining the faculty of the University of Texas at Austin in 1982.

Dr. Liechti’s main areas of teaching and research are in the mechanics of materials and fracture mechanics. He is the author or coauthor of papers on interfacial fracture, mechanics of contact, adhesion and friction at smaller and smaller scales, and the nonlinear behavior of polymers. He has consulted on fracture mechanics problems with several companies.

He is a fellow of the Adhesion Society, the Society of Experimental Mechanics, the American Society of Mechanical Engineers and the American Academy of Mechanics and an associate fellow of the American Institute of Aeronautics and Astronautics. He the joint editor of the journal of the Mechanics of Time-Dependent Materials. He was the 2015 recipient of the Adhesion Society’s Award for Excellence in Adhesion Science, sponsored by 3M. More recently, Dr. Liechti was the recipient of the Murray Medal from the Society of Experimental Mechanics in 2017.

Blurb

This revised and updated second edition is designed for the first course in mechanics of materials in mechanical, civil and aerospace engineering, engineering mechanics, and general engineering curricula. It provides a review of statics, covering the topics needed to begin the study of mechanics of materials including free-body diagrams, equilibrium, trusses, frames, centroids, and distributed loads. It presents the foundations and applications of mechanics of materials with emphasis on visual analysis, using sequences of figures to explain concepts and giving detailed explanations of the proper use of free-body diagrams. The Cauchy tetrahedron argument is included, which allows determination of the normal and shear stresses on an arbitrary plane for a general state of stress. An optional chapter discusses failure and modern fracture theory, including stress intensity factors and crack growth. Thoroughly classroom tested and enhanced by student and instructor feedback, the book adopts a uniform and systematic approach to problem solving through its strategy, solution, and discussion format in examples. Motivating applications from the various engineering fields, as well as end of chapter problems, are presented throughout the book.

• Continues emphasis on design including dedicated sections in the chapters on axially-loaded bars, torsion, and stresses in beams, and adds new sections on shear stresses in built-up beams, the moment-area method, and the application of singularity functions;
• Reinforces concepts with problems following each section and over 1000 figures and tables;
• Promotes students’ understanding the concept of isotropy in a revised section on stress-strain relations;
• Emphasizes the importance of visual analysis, particularly through the correct use of free-body diagrams.
