EXPERIMENTAL ANALYSIS OF CIRCULAR DISC WITH DIAMETRAL SLOTS

Discs are important structural elements in engineering application such as pressure vessel, missiles and liquid container. The turbine, brake disc and diaphragm clutch spring are the well- known examples for the industrial application of the annular plate with radial slots. The natural frequencies of component are of great interest in the analysis for response of structures to various excitations. Annular discs are fundamental structural elements studied in ocean engineering applications from offshore platforms to under water acoustic transducers. In various papers, study of annular discs with outer radial slot is done with t he help of classical plate theory and most of the experimental work is carried out with help of optical electronic speckle pattern interferometer method.
