The solution for a pressurized hollow poroelastic cylinder subjected to a ramping internal pressure, pi, is employed to interpret laboratory burst tests on 'thin-walled' cylinders of fluid saturated rocks. It is shown in the paper how a testing program based on thin-walled cylinders could be used to critically assess the validity of the 'Strength of Materials' interpretation of the breakdown and examine whether or not tensile failure is controlled by a Terzaghi effective stress. This in turn will help validate existing breakdown equations used in hydraulic fracturing stress measurements.
