young's modulus

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

RE: young's modulus

Some references give the value of E as 29 million psi, 29.5 million psi, or 30 million psi.  However E is independent of the Yield Stress.

Thanks eureka,
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.

RE: young's modulus

What about the E of stainless?>

RE: young's modulus


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.

RE: young's modulus

It would seem that using the lesser value of 29ksi would be conservative.
