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.
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,
