Finite Element Introduction

In this chapter we introduce the topic of finite element analysis for beam vibration. In Chap.  8 we described continuous models based on Euler-Bernoulli beam theory. This is a reasonable approach for a simple geometry, such as the cylindrical shaft in a

Preface

In this second edition textbook, we describe essential concepts in the vibration analysis of mechanical systems. The book incorporates the fundamentals of modal analysis, beam theory, and finite element analysis, as well as the required mathematics and experimental techniques, into a unified framework that is written to be accessible to undergraduate students, researchers, and practicing engineers alike. This book is based on undergraduate courses in mechanical vibrations that we have previously offered and developed the text to be applied in a traditional 15-week course format. It is appropriate for undergraduate engineering students who have completed the basic courses in mathematics (through differential equations) and physics and the introductory mechanical engineering courses including statics, dynamics, and mechanics of materials. We organized the book into ten chapters. The chapter topics are summarized here. • Chapter 1—We introduce the types of mechanical vibrations, damping, and periodic motion. • Chapter
