For some metal alloy, a true stress of 415 MPa produces a plastic true strain of 0.475. How much does a specimen of this material elongate when a true stress of 325 MPa is applied if the original length is 300 mm

Explanation:

= True stress = 415 MPa

= True strain = 0.475

= Original length of the alloy = 300 mm

Let us assume n = Strain hardening component = 0.25

K = Constant

True stress is given by

Now

True strain is given by

Elongation of material is .

the clapeyron equation (also called the clausius-clapeyron equation) relates the slope of a reaction line on a phase diagram to fundamental thermodynamic properties.
