†The apparent elastic limit is reported for those materials which permanently bend prior to rupturing.
*The modulus of rupture (MOR), m, determines the size of the window needed to withstand a pressure, p.
For a four times safety factor, the thickness of a mounted window, t, with an unsupported diameter, d, is:
tclamped = 0.866 d (p/m)1/2
tunclamped = 1.05 d (p/m)1/2
