Overstrain Tests on Thick-Walled Cylinders

Abstract

The experimental work described in the following covers pressure-expansion tests on thick-walled, closed-end cylinders of four different steels. The tests covered stress levels through the plastic and strain-hardening ranger to destruction, at pressures up to 100,000 psi. A theoretical method is given for computing expansion and bursting strength, based on both tension and torsion data. Finally, a simplified formula for ultimate pressures is described and checked against the experimental data.
