RE: [PSUBS-MAILIST] Hemisphere Seat Formula



Title: Re: [PSUBS-MAILIST] Hemisphere Seat Formula

Jon,

 

The books I (and you) know dont say anything about that.

If flat enough (both machined), I think you can calculate with all the surface.

For a dome calculated with the GL table, I found out that the pressure is about half the max allowable pressure of 110 N/mm^2

No replies.  Let me try another way...those of you with hemisphere
domes, how did you calculate the seat requirements?  I don't think total
surface area of the dome can be used to find the total stress on the
steel seat.
