Hi All, structural engineer here, so a bit out of my league.
I am trying to manufacture some Z profiles with a radius is the strong direction.
The Z is 2 flanges of 3/4 and a web of 1 3/4 inches. The thickness is 0.080 inches Lengths are about 8-9 feet.(12 ga) I chose 2024-T3 as the material.
I did a test today with a roll bender with custom dies and some material I had bent from some sheet aluminum and it failed. Imagine the stringers in an airplane or the wall members in a rail car - they have a varying radius along their length. SKin is attached to the outside and interior finish is attached on the inside.
I know its possible because I have some old samples from some 1950's construction that we are trying to re-create.
I'm looking for help on what tooling would do this, is there any standard extrusion out there? Really any advice would help.
Thank you in Advance
