Hello,

I have queries aboout WRC107 format and Pm as follows:

#1:
WRC107 output is showing stress label "Rad. Pm/Pl/Q". Why not showing "Circ. Pm/Pl/Q" ?

#2:
In stress summation section, why "Long. Pm" = "Rad. Pm"?. My understanding is "Long. Pm" (longitudinal stress due to pressue) should be half of "Rad. Pm" (hoop stress due to pressure)

Can any one from Integraph to reply my questions?

Thanks

Please describe how you produced the label "Rad. Pm/Pl/Q". When I use the WRC 107 processor, I see Circ. & Long.:

Hi Dave,

I see as below picture:

By the way, in stress summation results I see Rad. Pm (SUS) = Long Pm (SUS). I think it should be Rad. Pm(SUS) = Hoop stress and Long. Pm(SUS) = half of Hoop stress

I see that the WRC 107 processor references "radial" for attachments to spherical shells.
For spherical shells, the two perpendicular P-sub-m (SUS) stresses (shown as radial & longitudinal or radial & tangential) are equal to your hoop term. It is with cylinders that longitudinal pressure stress is half the hoop stress.

It's clear now.

Thank you
