This expanded and fully updated Handbook contains new results and adds some significant modifications, most notably a new section on ""Negative Stiffness and Damping,"" which is critical for understanding dynamic processes in mechanical systems. The book will be useful for practicing engineers working in the field of machine design, design of machine elements, machine dynamics, mechatronics, robotics and precision engineering. It will also be a useful reference for educators, as well as advanced undergraduate and graduate students. Praise for the previous edition: ""...a very detailed and comprehensive discussion of stiffness and damping in structures and structural elements...a great addition to the reference library of any practicing structural or design engineer."" AIAA Journal ""[This book] is well written and would make an excellent reference book and a textbook for review and continuing education courses on the subject."" ??Applied Mechanics Reviews
