Abstract:

The stability of simply-supported cylindrical panels under lateral pressure is investigated by linear theory. First, panels with classical simple supports are analyzed with the usual Donnell 8th order equation. Numerical results are presented which confirm that panels may buckle at lower pressures than corresponding complete cylindrical shells. Then the effect of circumferential restraint along the straight edges is studied by analysis of a panel with SS4 u v o boundary conditions and comparison with classical SS3 u N sub phi O supports. The coupled Donnell equations are reduced to a set of algebraic equations and the eigenvalues are solved by an iterative technique. Circumferential restraint along the straight edges results in considerable stiffening under lateral pressure.
