6. The flow curve equation for a material is given as follow. Plot the engineering stress-strain curve for the material. Label the plot properly. 0 = 552.7 €0.2 MPa [Hint: Transform the flow curve equation to engineering stress-strain equation]
2) Draw two schematic graphs using pencil showing a typical stress-strain curve for aluminum. The first graph should show engineering stress vs engineering strain, and the second graph should show true stress vs true strain. Label the showing: (i) elastic modulus (ii) proportional limit (iii) yield stress (iv) yield strain (v) fracture stress (vi) fracture strain on each graph. You may show both graphs on one plot. (5 points)
