  Free Vibration Analysis of Circular Perforated Laminated Plates

  By M. L. Pavan Kishore, K. Manohar Reddy, M. Avinash, G. Srinivasa Gupta

  Abstract: This study investigates the free vibration characteristics of circular perforated laminated composite plates. A finite element model is created to analyze the effects of perforation patterns, hole sizes, and laminate configurations on the natural frequencies and mode shapes of these structures. The model incorporates shear deformation theory and accounts for the anisotropic nature of composite materials. Parametric studies were held to examine how varying perforation geometries, including hole diameter, spacing, …
