Abstract :In the present study Navier method with generalized shear deformation theory for exponential model which proposed by Aydoğdu [31] is used to determine the natural frequencies and critical buckling loads of elastic plates. According to the model the transverse shear strains through the thickness direction of the plate are distributed exponential and the theory accounts the rotary inertia. The convergence and comparison studies demonstrate the accuracy and correctness of the present study. The results are obtained for comparing the antisymmetric and symmetric cross-ply laminated plates with isotropic and orthotropic plates for simply supported boundary condition. The material anisotropy, plate geometry insert ignore into journalissuearticles values(side-side, side-thickness);, variation of higher frequencies, and variation of vibration and axial buckling mode shapes are compared
