Free and Forced Vibrational Behavior of a Circular Annular Plate with Multiple Circular Holes: An Analysis Employing FEA

In mechanical components, circular plates with holes and patches are frequently utilized.The inherent frequencies and mode shapes of a circular plate are significantly altered when a patch or hole is present.This research uses finite element analysis (FEA) to study the vibrational behavior of annular circular plates with numerous circular holes.The temperature is maintained at a steady level.The impact of Eigen frequency on aspect and radii ratios is examined for several annular circular plates.These plates are analyzed using the free-free and clamped-free boundary conditions.The parametric investigations are carried out, and the outcomes are examined and noted.
