Young's modulus vs tangent modulus vs secant modulus
Young's modulus vs tangent modulus vs secant modulus
(OP)
Hai,
1)What is the difference between young's modulus, tangent modulus and secant modulus?
The understanding I have is,
Young's modulus represents the ratio of stress versus strain(slope) in the elastic range.
Tangent modulus and secant modulus represents the ratio of stress versus strain in the inelastic range and it has to be specified based on the value of stress value.
2)My second question, I have the values of secant modulus and tangent modulus, is there any way to find young's modulus of the material from these values.
If there is anything technically wrong with my question, please correct me.
With advanced Thnaks and Regards,

(d(sig)/d(e)) of the stress-strain curve, while the secant modulus (if my memory is correct) is the modulus from 0,0 to e(i), sig(i). By that definition (if I've gotten it correct), the secant modulus at a low strains approaches the Young's modulus, since Young's modulus is the linear modulus and at linear strains the secant modulus would directly be E.

Sorry--sig being stress, e being strain

Thanks for another great response, Brad, even though it wasn't my question...
