Mechanical Vibrations I

This textbook represents the Mechanical Vibrations lecture course given to students in the fourth year at the Department of Engineering Sciences (now F.I.L.S.), English Stream, University Politehnica of Bucharest, since 1993.

This book is application oriented and limited to what can be taught in an one-semester (28 hours) lecture course. It also contains material to support the tutorial that includes the use of finite element computer programs and basic laboratory experiments. The course syllabus changed in time due to the growing use of computers. We wrote simple finite element programs to assist students in solving problems as homework. The course aims to: (a) increase the knowledge of vibration phenomena; (b) further the understanding of the dynamic behaviour of structures and systems; and © provide the necessary physical basis for analytical and computational approaches to the development of engineering solutions to vibration problems.

The first volume, published in 2006, treats vibrations in linear and nonlinear single degree of freedom systems, vibrations in systems with two and/or several degrees of freedom and lateral vibrations of beams. Its content was limited to what can be taught in an one-semester (28 hours) lecture course, supported by 28 hours of tutorial and laboratory.
