Vibration of Structures and Machines (eBook, PDF)

Practical Aspects

• Format: PDF

Produktbeschreibung

This book addresses important practical aspects of nonlinear vibration analysis. It presents cases of considerable interest for researchers and practical engineers, such as rotor dynamics and torsional vibration of engines. The book can be used as both a reference and a graduate-level text, as it develops the subject from its foundations and contains problems and solutions for each chapter.
