2014 T6511 extrusion plastic bending LT
(OP)
Hello all.
Anybody have a reference for 2014 T6511 extrusion plastic bending in the LT direction? Everything I see is for the L direction.
Since Ftu is the same for both the L and LT directions, could I use the charts for the L direction and reason it that way?
Thanks.

I'm just asking for a sanity check for using the L plastic bending curves for LT for sections less than .5 thick.

I gotta say that i'm alittle suspicious of plastic bending in the LT direction of an extrusion ...

I'm looking at cargo system restraint components.
My solution is to move things around on the pallet to get the reaction loads down. The Douglas layout centered the locks on the pallet sides. The config I'm working on pushed everything forward so that I'm getting a high load on the aft most side restraint when I have an aft CG.
Of course, this config has been around for 20 years, so there's going to be squawking and gnashing of teeth. Not to mention the inertia load factors were pulled out of the air with no check of available load factor data. And shear due to bending was calculated as V/A... Kind of hard to go back to mahogany row and say this thing's AFU.

something to consider might be that if you're section is going plastic (ie above linear bending) would another loadpath become active ?
it can be a struggle to make something that has been around for donkey's years "correct", but that's why we get paid the big bucks ! ... keeping other people's a$$es out of the fire

I could live with the 2014 extrusion, provided the assembly is installed per the Douglas layout.
