Abstract A pressure vessel with four radial windows was designed in which to conduct equation-of-state experiments at pressures up to 1 GPa (145,000 psi). To determine the relative safety of the vessel, the stress distribution in the cylindrical sidewalls, particularly the stress concentration near the window openings, was studied. Conventional analysis was used for the initial evaluation but was found to give somewhat higher stress values than were actually present. Better determinations of the stress distribution were obtained by photoelastic analysis of a model of the pressurevessel linear and by proof tests with strain gages of the actual liner and the assembled pressure vessel. Apparently, the tapered sapphire windows, loaded in compression by the internal pressure in the vessel, modify the stress distribution sufficiently to allow operation at higher pressures than otherwise would be attainable. Design features of the pressure vessel are presented, together with a synoptic stress analysis, a photoelastic analysis, and results of the strain-gage studies.
