- Abstract
- Buckling and postbuckling behaviour of composited skew plates while compressing and shearing were analyzed. The plan view of plate is a parallelogram with different boundary condition along the contour. The problem of buckling is solved in movement by dint of Reitz method. While analysis of the post buckling behaviour of a plate the surface shape has been taken equal to first own mode of buckling. Displacements in each point have been computed with the use of the well-known finite difference method. Load-carrying capacity of the plate has been calculated with the use of the Tsai-Wu criterion. Influence of skew panels, structure of reinforcing and boundary conditions of panels on buckling and load-carrying capacity were investigated. Rational structures of reinforcing were obtained to provided maximal critical and collapse forces for composite symmetric panels.
