Athick spherical pressure vessel of inner radius 150 mm is subjected to maximum an internal pressure of 80 mpa. calculate its wall thickness based upon the (a) principal stress theory, and (b) total strain energy theory. poisson's ratio = 0-30, yield strength 300 mpa.
Answers: 2
= 150 mm![r_{1}\left [ (\frac{\sigma _{y} +p}{\sigma _{y} - 0.5p})^{1/3}-1 \right ]](/tpl/images/0109/2385/7914d.png)
= 3.75
= 170.36 mm
