Let's simplify the stress-strain curve of a material with two straight lines. One from the origin up to the elastic limit (εy, σy), and the second from this point until rupture (εu, σu).
Assume εy = 0,4 %; σy = 464 MPa; εu = 16,6 %; σu = 634 MPaStart by writing the equation for the whole curve (one straight line for each region of the curve: two straight lines).Give the Young's modulus in GPa.
