The application of incremental plasticity conditions in the axisymmetric problem of a spherical tank loaded with internal and external pressure is considered. Inhomogeneous stress distribution leads to increased limiting gradient stresses, which depend on the internal cavity size. For the tanks of real dimensions, the magnification limits are established for different laws of approximation of the deformations’ constraint gradient effect.
