I am working on a baffle cracking problem for an oil tank on a military helicopter. I am looking for a da/dN curve for 6061-T6 Al plate (0.090 thickness). The max. use temp is 350F, but obviously I'll take RT if that is all there is available (any idea the best parameter to ratio by for temp correction?).
I understand that this crack growth curve is in NASGRO 4.0 and later (the mat code is M6AB13AB1). If anyone ot there has access to this F/M data, it would be greatly appreciated. Please respond to my post or feel free to contact me directly at dtc@psnet.com. Thank you very much for your time.
