Analysis of Free Vibrations of a Skew Orthotropic Composite Panel

The free vibrations and stability of layered skew composite panels symmetrical in thickness are considered. The panel is modeled by a plate that has the shape of a parallelogram in plan view, each edge of which can have an independent way of fastening. The solution of the problem of transverse vibra...

Description
Summary:The free vibrations and stability of layered skew composite panels symmetrical in thickness are considered. The panel is modeled by a plate that has the shape of a parallelogram in plan view, each edge of which can have an independent way of fastening. The solution of the problem of transverse vibrations and stability is carried out in displacements by the Ritz method. The values of the natural frequencies and the critical compression forces of skew layered composite panels with different boundary conditions depending on the geometry of the element, boundary conditions, and levels of the axial load are obtained.
