Grain orientation on flat parts
Grain orientation on flat parts
(OP)
Should grain orientation on a 1/8" thick 2024-T3 aluminum plate be considered when designing a flat component (such as a strap) which will not be bent?
I am building a Rutan designed aircraft and I am milling the elevator hinge brackets on the canard. They are "L" shaped, with the vertical section of the "L" burried in the canard and the horizontal protruding out of the aft and into the elevator (so the horizontal section of the "L" is catilever). The grain orientation is not specified in the plans and I don't think it is an issue but I want ot learn more about the subject of grain orientation on milled parts.

RE: Grain orientation on flat parts
Without having a detailed drawing of the part, it is hard to provide a recommendation as to whether orientation is really significant here or not. Typically, if it is not specified on the drawing, or in the parts list, then the design/analysis has already accounted for the worst conditions. Check other drawings, see if they have specific orientations required.
Best luck.
