Textbook in PDF format

In writing this book, the author’s main intention was to write a concise exposition of the fundamental concepts and ideas that, directly or indirectly, underlie and pervade most of the many specialised disciplines where linear engineering vibrations play a part.
The style of presentation and approach to the subject matter places emphasis on the inextricable – and at times subtle – interrelations and interplay between physics and mathematics, on the one hand, and between theory and applications, on the other hand. In this light, the reader is somehow guided on a tour of the main aspects of the subject matter, the starting point being (in Chapter 2, Chapter 1 is for the most part an introductory chapter on some basics) the formulation of the equations of motion by means of analytical methods such as Lagrange’s equations and Hamilton’s principle. Having formulated the equations of motion, the next step consists in determining their solution, either in the free vibration or in the forced vibration conditions. This is done by considering both the time- and frequency - domain solutions – and their strict relation – for different types of systems in order of increasing complexity, from discrete finite degrees-of-freedom systems (Chapters 3 and 4) to continuous systems with an infinite number of degrees-of-freedom (Chapter 5). Having obtained the response of these systems to deterministic excitations, a further step is taken in Chapter 6 by considering their response to random excitations – a subject in which, necessarily, notions of probability theory and statistics play an important role.
