| dc.description.abstract | Dynamic characterization of cantilevered cracked plates assumes importance for a variety of applications including aging aerospace, mechanical and ship structural components. In this paper modal characteristics of isotropic plates with damage identified as cracks are investigated. The paper describes results obtained by finite element simulation of cracked plates. The frequency degradation as a function of the crack length is presented for selected aspect ratios. Some damage metrics are developed based on the modal parameters to describe the structural integrity of the plate type structures with root cracks. Frequency response analysis is presented to show the effect of the crack growth on the response of the plates. Some suggestions are developed based on the observations of the simulation for health monitoring of structural components. | en_US |
