Mechanical Vibrations Theory and Applications :: By Graham Kelly :: Book and Solution :: Engineers apply mathematics and science to solve problems. In a traditional undergraduate engineering curriculum, students begin their academic career by taking courses in mathematics and basic sciences such as chemistry and physics. Students begin to develop basic problem-solving skills in engineering courses such as statics, dynamics, mechanics of solids, fluid mechanics, and thermodynamics. In such courses, students learn to apply basic laws of nature, constitutive equations, and equations of state to develop solutions to abstract engineering problems.
Vibrations is one of the first courses where students learn to apply the knowledge obtained from mathematics and basic engineering science courses to solve practical problems.
While the knowledge about vibrations and vibrating systems is important, the problem-solving skills obtained while studying vibrations are just as important.
The objectives of this book are twofold: to present the basic principles of engineering vibrations and to present them in a framework where the reader will advance his/her knowledge and skill in engineering problem solving.
This book is intended for use as a text in a junior- or senior-level course in vibrations. It could be used in a course populated by both undergraduate and graduate students.
The latter chapters are appropriate for use as a stand-alone graduate course in vibrations. The prerequisites for such a course should include courses in statics, dynamics, mechanics of materials, and mathematics using differential equations.
Some material covered in a course in fluid mechanics is included, but this material can be omitted without a loss in continuity.

Chapters in depth
Chapter 1 is introductory, reviewing concepts such as dynamics, so that all readers are familiar with the terminology and procedures.
Chapter 2 focuses on the elements that comprise mechanical systems and the methods of mathematical modeling of mechanical systems.
It presents two methods of the derivation of differential equations: the free-body diagram method and the energy method, which are used throughout the book.
Chapters 3 through 5 focus on single degree-of-freedom (SDOF) systems.
Chapter 6 is focused solely on two degree-of-freedom systems.
Chapters 7 through 9 focus on general multiple degree-of-freedom systems.
Chapter 10 provides a brief overview of continuous systems.
The topic of Chapter 11 is the finite-element methods, which is a numerical method with its origin in energy methods, allowing continuous systems to be modeled as discrete systems.
Chapter 12 introduces the reader to nonlinear vibrations, while Chapter 13 provides a brief introduction to random vibrations.
The references at the end of this text list many excellent vibrations books that address the topics of vibration and design for vibration suppression.

There is a need for this book, as it has several unique features:
Two benchmark problems are studied throughout the book. Statements defining the generic problems are presented in Chapter 1.
Assumptions are made to render SDOF models of the systems in Chapter 2 and the free and forced vibrations of the systems studied in Chapters 3 through 5, including vibration isolation.
Two degree-of-freedom system models are considered in Chapter 6, while MDOF models are studied in Chapters 7 through 9.
A continuous-systems model for one benchmark problem is considered in Chapter 10 and solved using the finite-element method in Chapter 11.
A random-vibration model of the other benchmark problem is considered in Chapter 13. The models get more sophisticated as the book progresses.
