I am analyzing stress on steel flat bar.

Few mechanical properties given by supplier ( YS, TS and Elongation). Based on that I derived the MoE, however it is different from 300+ MPa Steel normal property.

300 plus

Yield strength  305 MPa

Ultimate Tensile Strength 490 MPa

Elongation 30% = 0.3

strain = dl / l = 0.3/100 =0.003

Modulus of elasticity = stress / strain = 305/ strain

      = 305/ 0.003

= 101666 MPa

= 102 GPa ( Normal 300+ MPa steel properties has MoE 200 GPa.

Does anyone come across this issue?

Thanks and Regards,
