Vibration of cracked plate using differential quadrature method and experimental modal analysis

In this study, the vibration of cracked plates is investigated using the differential quadrature method and experimental modal analysis. The crack, which is assumed to be open, is modeled by the extended rotational spring. With its finite length, the crack divides the plate into six segments. Then, the differential quadrature is applied to the governing differential equations of motion and the ...

Experimental Modal Analysis

SOUND AND VIBRATION/JANUARY 2001 Often times, people ask some simple questions regarding modal analysis and how structures vibrate. Most times, it is impossible to describe this simply and some of the basic underlying theory needs to be addressed in order to fully explain some of these concepts. However, many times the theory is just a little too much to handle and some of the concepts can be d...

A New Method for Vibration Modal Analysis

INTRODUCTION This paper is about a new method for vibration modal analysis, which is called the smooth orthogonal decomposition (SOD) based modal analysis method. The proper orthogonal decomposition (POD) based modal analysis method, which was first proposed by Feeny et.al in 1998, indicates an exciting method for extracting the modal shapes of a vibration system by using only the output displa...
