 | By Yong Bai and Zhao-Dong Xu Copyright: 2019 | Status: Published ISBN: 9781119605607 | Hardcover | 473 pages Price: $249 USD  |
One Line Description
Written by two experts across multiple disciplines, this is the perfect reference on structural dynamics for veteran engineers and introduction to the field for engineering students.
Audience
Structural engineers, civil engineers, ocean engineers, mechanical engineers, industrial engineers, petroleum engineers, production engineers, and engineering students across multiple disciplines
Structural engineers, civil engineers, ocean engineers, mechanical engineers, industrial engineers, petroleum engineers, production engineers, and engineering students across multiple disciplines
Description
Across many disciplines of engineering, dynamic problems of structures are a primary concern. Civil engineers, mechanical engineers, aircraft engineers, ocean engineers, and engineering students encounter these problems every day, and it is up to them systematically to grasp the basic concepts, calculation principles and calculation methods of
structural dynamics. This book focuses on the basic theories and concepts, as well as the application and background of theories and concepts in engineering.
Since the basic principles and methods of dynamics are applied to other various engineering fields, this book can also be used as a reference for practicing engineers in the field across many multiple disciplines and for undergraduate and graduate students in other majors as well. The main contents include basic theory of dynamics, establishment of equation of motion, single degree of freedom systems, multi-degree of freedom systems, distributed-parameter systems, stochastic structural vibrations, research projects of structural dynamics, and structural dynamics of marine pipeline and risers.
Whether for the veteran engineer or student, this is a must-have for any scientific or engineering library.
