![]() Data and Analysis for a Tension Test on AISI 1020 Hot-Rolled Steel (a) Test Data (b) Calculated Values Engr Engr. (d) Calculate corrected values of true stress, and plot the resulting stress-strain curve. (c) Calculate true stresses and strains, and plot the true stress-strain curve. Also, what would be the new length of the original 50.8mm gage section? Discuss the results. ![]() Estimate the elastic strain recovered and the plastic strain remaining. (b) Assume that the test was interrupted upon reaching a strain = 0.0070, and the specimen unloader to zero force. (a) By plotting corresponding engineering stress-strains diagram determine the following materials properties: elastic modulus, 0.2% offset yield strength, ultimate tensile strength, percent elongation, and percent reduction in arca. (3) The fina minimum diameter in the necked region was 5.28 mm. (2) Similar marks originally 50.8mm apart were 70.9mm apart. After fracture, the broken halves were reassembled, and the following measurements were made: (1) Marks originally 25.4mm apart and on opposite sides of the necked region were 38.6 mm apart due to the lengthwise stretching in the specimen. In addition, minimum diameters were measure manually with a micrometer in the necked region at several points during the test. For strain, the extensometer gage length was L = 50.8 mm. Representative test data are given in Table (a) in the form of force and engineering strain. Transcribed image text: A tension test was conducted on a specimen of AISI 1020 hot-rolled steel having an initial diameter of 9.11 mm.
