RUPTURE SURFACES OF THICK SPHERICAL SHELL UNDER INTERNAL PRESSURE,

Abstract

The theory of fracture on surfaces of instability has been applied to predict, analytically the possible surfaces on which a thick-walled spherical shell will ruputure. The shell is assumed to be made of an incompressible, rigid-perfectly plastic material satisfying either Tresca or von Mises yield criterion. Furthermore, it is assumed that the internal pressure is sufficient to render the shell material fully in the plastic state. Under these conditions, it is shown that the spherical shell is subject to ruputure on radial planes whose intersections with the inner and outer surfaces of the shell are arcs of great circles.
