โœฆ Synopsis

The stability of a simply supported square plate with openings under in-plane loading is analysed using a Finite Element program BUCSAP (BUCkling Structural Analysis Program). The openings are considered as square and central for the main study but rectangular and central for comparison with other work. Different magnitudes of tension and compression are assumed as initial pre-stress in the transverse direction before the longitudinal stress is applied. Two load cases have been considered. The longitudinal stress is assumed as uniform compression for Case I and is assumed as trapezoidal compression representing hydrostatic loading for Case 2. The results have been used to plot design charts.

This paper describes a method of determining the effects of openings on the fundamental frequencies in plates with different types of boundary conditions. By extending the grid framework model, the finite difference operators can be developed for the re-entrant corner, junction point, etc., without

Equations of motion for antisymmetric angle-ply plates in a general state of non-uniform initial stresses, where the effects of transverse shear and rotatory inertia are included, are derived by using Trefftz equations and the variational principle. These equations are then non-dimensionalized to a
