Bursting of Brittle Materials due to Penetration of Pressure Fluid : 1st Report, Experiment

Abstract

To study the effect of penetration of pressure fluid on the bursting of brittle materials, the experiments were carried out with cast iron hollow cylinders under internal, lateral fluid and external pressures, and the leakage and the bursting pressures were measured quantitatively. Pressure fluid used in this experiment is turbine oil (#32), and the experiments were carried out with cylinders coated on the inner surface or the outer one or not coated. From these experiments it is made clear that the leakage and the bursting pressures of the cylinders are influenced by the stress distribution in the cylinder and the rate of increasing pressure of internal pressure.
