A-286 STRESS-STRAIN CURVE
A-286 STRESS-STRAIN CURVE
(OP)
Can anyone out there supply me the above info, or points from which the Ramberg-Osgood equation can be formulated?
I cannot find what I need in any of the handbooks to which I have access.
Thanks in anticipation.

From "Aerospace Struc. Met. Handbook", tensile and compression stress-strain curves for A-286 sheet.

Probably, you'll already have this one, but here it is the properties table from MIL-HDBK-5
RE: A-286 STRESS-STRAIN CURVE
E*strain/f.7 = (stress/f.7) + (3/7)*(stress/f.7)^n
n = 1+ln(17/7)/ln(f.7/f.85)

ftu = 140ksi, fcy = 95ksi, E = 29E6psi, n = 15, f.7 = 93ksi
