Abstract

Six experiments were performed on mild steel models which confirm that the presence of external loads (axial force, coplanar moment, and shearing force) lowers the plastic limit pressure-carrying capacity of outlet connections from spherical pressure vessels. Excellent agreement is observed between experimental results and theoretical predictions obtained from lower-bound rigid plastic analysis. Similar agreement with upper bound analysis is obtained in the case of axisymmetric loading.
