An Analysis of the Dynamic Behavior of Circular Plates from a Damage Detection Perspective
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2014, Vol 11, Issue 1
Abstract
This paper presents a study regarding the dynamics of thin circular plates, embedded on the circumference. A finite element analysis (FEA) as well as analytical investigations is performed, and the results in terms of frequencies and mode shapes are used to highlight the plate’s dynamics. First we demonstrated the good fit between the results obtained in different ways. Analyzing the plate’s dynamic behavior, we identified vibration modes able to be used to extract patterns characterizing a damage location. These damage signatures can be used, similar as in the case of beams, to find the damage location.
