young's modulus
young's modulus
(OP)
Hi everyone,
does the modulus of elasticity of steel vary with yeild strength???
I am working on astructure that is to be built with Grade 70 weathering steel (Fy=70ksi) is the "E" value 29000000psi or higer??
I really would appreciate your respose
Thank you all

that is what i have always known and thought but I have seen the value of 40 million psi in several places for grade 70 which is got me wondering,
thanks though.

FYI, the E of steel strand and rope is less due the "spring" effect of the rope/strand twist/helix...
E strand is about 20,000 ksi
E rope is about 25,000 ksi
BUT...the E of high tensile THREADED bar (ASTM A722) varies excessively from ASTM standard value of 29,700 ksi.
