Transverse vibrations of simply supported rectangular plates with two rectangular cutouts

Slobodne Vibracije Pravougaonih Ploča Sa Otvorima Primjenom Metoda Konačnih Traka

“…The code is built upon software LEDA presented in [ HYPERLINK \l "Bor131" 2 ]. The numerical research includes simply supported squared plates with two rectangular cutouts, 3 ], with disposition of cutouts as in Figure 3. The plates were modeled with 20 strips and three cells in longitudinal direction.…”

“…One of the main drawbacks of this method is its inability to describe discontinuities such as abrupt changes of thickness, cutouts and similar. Some authors already dealt with this problem, using the negative stiffness approach, 2 ], [ HYPERLINK \l "Bui09" 3 ], 4 ]. Only the free vibration and buckling analyses are performed since, for them, the effects of localization and stress concentration can be ignored without prejudicing the accuracy of the solution.…”

Modeling and Simulation of Transverse Free Vibration Analysis of a Rectangular Plate with Cutouts Using Energy Principles

“…The position and number for cutouts in the flexible plate have great influence on the vibration characteristics of structure [1][2][3][4][5][6][7]. The rigidity of the flexible plate with cutouts is depended mostly upon the number of cutouts [1,2].…”

“…The rigidity of the flexible plate with cutouts is depended mostly upon the number of cutouts [1,2]. Avalos et al [1] have investigated the transverse vibration of rectangular plate with a rectangular cutout.…”

Independent Coordinate Coupling Method for Free Vibration Analysis of a Plate With Holes

“…Kim et al(1987) performed the theoretical analysis on a stiffened rectangular plate with a hole. Avalos and Laura(2003) calculated the natural frequency of a simply-supported rectangular plate with two rectangular holes using the classical Rayleigh-Ritz method. Lee et al(1994) analyzed a square plate with two collinear circular holes using the classical Rayleigh-Ritz method.…”
