Dynamic Analysis of Thin Plates with Defects by Experimental and FEM Methods
Journal Title: Romanian Journal of Acoustics and Vibration - Year 2013, Vol 10, Issue 2
Abstract
In this paper an analysis regarding the dynamics of thin rectangular plates embedded on all edges is presented; aiming to highlight the effect of defects upon their natural frequencies. The first thirty natural frequencies were obtained for a plate without defect and the same plate with four different types of defect. It was placed in the corner of the plate; one dimension (the length of defect) was increased successively. The results in terms of frequencies and mode shapes are finally presented from all values obtained in tabular form, were prepared graphs to compare the results and highlighting the way how natural frequencies changes due to defect. Finally, the results are compared with measurements, in order to demonstrate the validity of the theoretical considerations.
