Assignment task: Please written by computer source
The following true stress-strain properties of a metal were obtained in a monotonic tensile test: E = 30 × 103 kpsi, n = 0.2, εf = 1.0 and σf = 270 kpsi. Determine the following quantities: (a) Strength coefficient K, (b) 0.2% offset yield strength Sy, (c) percent reduction in area %RA. Plot the monotonic true stress-strain curve (Matlab or Excel).
