Notes:
Systematic tests of failure have been performed up to 700 MPa on 75 cylindrical sapphire windows of various thicknesses in the Poulter unsupported area geometry. Three distinct failure patterns are found to occur. The influence on the bursting pressure of the c-axis orientation, annealing, and fatigue are reported and discussed. Maximum working pressures are determined, as a function of the ratios of thickness and unsupported area diameter, to the window's diameter.
