In this study, the natural frequencies of the perforated square plate with a square penetrationpattern are obtained as a function of ligament efficiency using the commercialfinite-element analysis code ANSYS. In addition, they are used to extract the effectivemodulus of elasticity under an assumption of a constant Poisson's ratio. The effectivemodulus of elasticity of the fully perforated square plate is applied to the modal analysis ofa partially perforated square plate using a homogeneous finite-element analysis model.
The natural frequencies and the corresponding mode shapes of the homogeneous modelare compared with the results of the detailed finite-element analysis model of the partiallyperforated square plate to check the validity of the effective modulus of elasticity. Inaddition, the theoretical method to calculate the natural frequencies of a partially perforatedsquare plate with fixed edges is suggested according to the RayleigheRitz method.
