Question details

Draw a true stress vs true stress curve for a typical metal. Draw an engineering stress vs engineering strain curve. Label the yield stress, ultimate tensile stress and Youngs modulus on the appropriate drawing; also clearly indicate the elastic region and the plastic region on the true stress-strain sketch. Why does engineering stress vs. engineering stress curve look different? a) b) Derive the burgers vector (length and direction) for an FCC lattice. Give your answer in terms of the unit cell and crystallographic direction. Please be specific and explain please and thank you
