4. (20") The stress-strain curve of a steel specimen is shown below. The specimen is loaded up to point A and unloaded. Suppose the stress and strain at point A is A = 405 MPa and EA = 0.025. a. Determine the Young's modulus (i.e. elastic modulus) of the steel specimen. b. Calculate the recoverable strain and plastic strain after it is uploaded from point A. 500 400 300 Stress (MPa) 200 100 0.000 0.001 0.002 0.003
