(5) Stress Intensities. For each of the categories of stress as
defined as acting at this point, the maximum stress intensities are
developed. For these particular set of stresses, the stress intensities
become:
Pm = 9,905 - 0 = 9,905 psi
PL = 29,371 - 0 = 29,371 psi
PL + Pb = 29,371 - 0 - 29,371 psi.
For the inner surface
PL + Pb + Q = greatest of
(9,905 - 11,852) - (29,371 - 3,555) = 27,863 psi
(29,371 - 3,555) - (-1000) = 26,815 psi
(-000) - (9,905 - 11,852)
= 948 psi.
Thus PL + Pb + Q = 27,863 psi on inner surface.
For the outer surface
PL + Pb + Q = greatest of
(29,371 + 3,555) - (0.0) = 32,926 psi
(9,905 + 11,852) - (29,371 + 3,5555) = 11,169 psi
(0.0) - (9,905 + 11,852) = 27,757 psi.
For the inner surface F = 0, thus
Thus PL + Pb + Q + F = 27,863 psi.
For the outer surface F = 13,054 in the [PHI] direction only; thus,
PL + Pb + Q + F = greatest of
(9,905 + 11,852 + 13,054) - (29,371 + 3,555 + 0) = 1,737 psi
(29,371 + 3,555) - (0.0) = 32,926 psi
(0.0) - (9,905 + 11,852 + 13,054) + 34,811 psi.
Thus for the outer surface
PL + Pb + Q + F = 34,811 psi.
