[Retracted] Free Vibration Analysis of Thick Rectangular and Elliptical Plates with Concentric Cut‐Out

Abstract

This research paper deals with a numerical method which is modified and applied, by the authors to derive an eigenvalue of a thick plate having cut-out in which geometries of plate and cut-outs are different, through a deflection matching condition by including shear deformation and rotary inertia effects, with less computational efforts and high accuracy. The modified Independent Coordinate Coupling Method (ICCM) is validated with FEM package (ANSYS) and applied to know the change in eigenvalues for a plate with cut-out by varying various parameters like aspect ratios, cut-out size, and thickness ratios. Trigonometric functions considered at the boundary level conditions of a simply supported plate should be satisfied. Free vibrational exploration on a thick isotropic plate with various aspect ratios and an elliptical plate with various sizes is carried out through the modified ICCM. Independent coordinates are applied for a plate domain and for a hole domain individually followed by equating the deflection condition of hole and plate, a reduced mass to express with cut-out from which eigenvalues can be obtained. The deflection matching condition facilitates the analysis even though the geometries of plate and cut-outs are different.

Experimental Investigation on Thermal Behaviors of Nanosilicon Carbide/Kenaf/Polymer Composite

“…As a function of time and temperature, the DSC determines material transitions. The thermal phase change of the composites is shown by the endothermic (heat absorption) and exothermic (heat release) peaks and magnitudes [19,20]. The sample shape and size, the temperature ramp, and the kind of environment can all have an impact on the results gathered by the DSC study.…”

Influence of cut-out shape on the dynamic behavior of carbon nanotubes reinforced functionally graded plates

“…Liew et al [14] and Dewangan et al [15] studied the flat and curved panel structures with cutouts and observed that geometrical parameter and cutout size are significantly influencing the structures' natural frequency. Merneedi et al [16] studied the free vibration behavior of rectangular as well as elliptical plates having cutouts. It is observed that by introducing cutout onto a structure can make it vibrate with other modes for same natural frequency.…”
