Vibration Characteristic of unstiffened and stiffened skew plates under In-plane loadings

Abstract: The vibration behaviour of unstiffened and stiffened skew plate subjected to uni-axial and bi-axial in-plane loadings is studied. As the applied in-plane loading is not uniform, the resultant plate in-plane stresses are evaluated from the plate membrane analysis. Using these stress distributions, partial differential equations governing the stability of skew plates are derived. The first order shear deformation (FSDT) theory is considered in the present formulation. Effects of skew angles, boundary conditions, number of stiffeners and uniaxial and biaxial types of loadings on the buckled vibration behaviour of the unstiffened and stiffened skew plate are investigated.
