a). Modulus of elasticity- E= slope of stress strain curve at 50% of peak that is at 228.33 MPa
considered point
212.2066 | 0.00206 |
247.3338 | 0.00246 |
E = (247.33-212.20)/(0.00246-0.00206)
E = 87.817 GPa
b) Proportion Limit
when stress reaches to 388.484 MPa, stress strain curve behave as nonlinear and that point is proportion limit.
hence proportion limit is 388.484 MPa
c).Yield Strength at 0.002 strain
to measure accurate yiels strength draw 0.002 offset like this
Yield strength is 430 MPa( mesured from aove figure
d) Ultimate strength is maximum peak stress of stress strain curve
i.e. fu = 556.66 MPa
As per HOMEWORKLIB POLICY 1st four part is done for rest of the parts you have to ask again and please upvote if you got yyour answer.. thank you!!11
