Good Day Colleagues,
I noticed that in two different aircraft company finite element manuals the light frames typically used in airliner fuselages
are represented by Nastran CRODS for the flanges of the stringer and a single QUAD4 element representing the web.

Hi All,
There is an interesting thread under Structural Engineering regarding checking of calculations; some of the replies are quite scary (think Hyatt Regency Walkway 1981).
How do you go about checking of calculations in the aerospace industry?
