STRESSES IN A PERFORATED CYLINDRICAL SHELL

Technical Report ·
OSTI ID:4029319

It is assumed that the deformations of a thin cylindrical elastic shell, subjected to a uniform lateral pressure, are adequately described by the Donnell shell equations. The surface of the shell is perforated by a rectangular cutout. The tangential membrane displacements and the normal membrane stresses vanish on the simply supported edges of the hole and the ends of the cylinder. Numerical solutions were obtained by replacing the boundary value problem by a finite difference approximation and solving the resulting system of linear algebraic equations by an iteration procedure.
