Compressed Elastomer Method for Internal Pressure Testing

Abstract

The compressed elastomer likethod is a safe and easy technique for generating high internal pressure for tubular samples. The approach compresses a cylinder of an elastomeric numerial and uses the Poisson's expansion to generate internal pressure. The equations needed to convert the axial force to the internal pressure are derived and the procedure is verified using a steel control sample. To date. pressures have been generated in excess of 340 MPa (50 ksi).
