Dynamic Analysis of Isotropic Annular Plate with Eccentric Hole Using Finite Element Method

Circular isotropic plates with number of holes are employed in various engineering application, especially in mechanical parts like gears, turbine wheels, circular saws, disc brakes, etc. In this study, an FEM technique is adopted for modal and harmonic analyses of circular plates with centre as well as eccentric holes. The steel material is used to define properties. The effect of increasing eccentric holes on frequency parameters and critical amplitude are also investigated. The element “Solid 185”, appropriate for modelling three-dimensional solid components, is used to mesh the model. The results are validated employing the required convergence analysis and checked with available literatures. From the comparison study, it has been demonstrated that the presently adopted model is suitable for analysing the annular plate structure, since the numerical results obtained in the present study are in good accordance with the published ones.
