Written by an expert engineer of over 40 years experience, the book comprehensively opens up the dynamic behavior of structures and provides engineers and students with a comprehensive practice based understanding of the key aspects of this key engineering topic.
Written with the needs of engineers of a wide range of backgrounds in mind, this book will be a key resource for those studying structural dynamics and vibration at undergraduate level for the first time in aeronautical, mechanical, civil and automotive engineering. It will be ideal for laboratory classes and as a primer for readers returning to the subject, or coming to it fresh at graduate level.
It is a guide for students to keep and for practicing engineers to refer to: its worked example approach ensures that engineers will turn to Thorby for advice in many engineering situations.
- Presents students and practitioners in all branches of engineering with a unique structural dynamics resource and primer, covering practical approaches to vibration engineering while remaining grounded in the theory of the topic
- Written by a leading industry expert, with a worked example lead approach for clarity and ease of understanding
- Makes the topic as easy to read as possible, omitting no steps in the development of the subject; covers computer based techniques and finite elements
Reference text/supplementary text for senior undergraduate and graduate students of aeronautical engineering plus mechanical, civil and related engineering disciplines; Graduates starting structural dynamics work
