Abstract: The equation of motion yields the characteristic equations for natural frequencies, buckling loads, and their corresponding mode shapes. The effects of stiffener position and number, aspect ratios, boundary conditions, stiffener parameters, and stiffener parameters on the buckling load parameter and fundamental frequency of stiffened plates are studied. The eccentricity of the stiffeners gives rise to axial and bending displacement in the middle plane of the plate.

Keywords: Vibration, Buckling, Equispaced stiffener, Stiffened plate.
