“…Trends of first six frequencies were discussed for five types of boundary conditions. Sabir and Davies [13] used finite element method to determine natural frequencies of flat square plates containing an eccentrically located square hole. Plates were subjected to in-plane uniaxial or biaxial compression or uniformly distributed shear along the four outer edges, which were either simply supported or clamped.…”

“…It is worthwhile to mention the use of FEA if there are necessary cutouts in a thin-walled structure as a functional requirement that weaken the affected part of the structures, thus compromising the structure's integrity, or if the stiffeners are reinforced the structure. Paper [13] is devoted to the natural frequencies of plates with square holes when subjected to in-plane uniaxial, biaxial or shear loading. Jafari et al [14] introduced the optimal values of effective parameters on the stress distribution around a circular, elliptical and quasi-square cutouts in perforated orthotropic plates under in-plane loadings.…”

“…Numerical results dealing with effect of parameters like side to thickness ratio, plate side to cutout ratio and anisotropy are presented for both linear and nonlinear frequencies. Sabir and Davis (1997) used the finite element method to determine natural frequencies of flat square plates containing an eccentrically located square hole. Sivakumar et al (1999a,b) studied free vibrations of composite laminates in the presence of cutouts.…”
