Shear flow
Shear flow
(OP)
Hi all,
Is there a way to view the shear flow along edges in FEMAP? There is a function in the NEi editor called shear flow but I haven't seen it in FEMAP. It seems like a quite basic function and something that would be used all the time (welds, rivets etc).
Problem: I need to determine on a basic stage the amount of bolts required along the edge between two panels (3D shells) that are connected. I was first thinking of using the element force FX, FY to obtain a force/length but it gives me somewhat different values than from the shear flow plot in the NEi editor and the more I search on the subject the more confused I get.
Cheers,
Daniel

RE: Shear flow
You could also enable Grid Point Force Balance in the Analysis set manager, then use free-body plots to evaluate nodal forces at an interface.

Don't you mean
element shear stress * thickness
or,
element force / thickness

Wouldn't FXY give only the shear component? I'm mostly worried about the normal force since the panels are mostly laterally loaded.
I think what I am really looking for (at this stage, initial design) is the actual in-plane force, principal or equivalent, since I know how much each bolt can take from analytical estimates.
Wouldn't the element load/length: FX and FY, plotted together as a combined vector give an indication on the amount of force the bolt line is subject to?
