Draw a typical stress vs strain tensile test curve for the following materials (two seperate graphs) and label the axis.
A ductile metallic test specimen that is stretched to failure displaying a characteristic yield point and show the following parts on the curve.
1- Yield point
2- Ultimate Tensile Strength
3- Breaking point
4- Elastic Region
5- Plastic Region
6- Necking region
The data shown in the table below were obtained from a tensile test of high-strength steel. The test specimen had a diameter of 13mm and a gage length of 50mm. At fracture, the elongation between the gage marks was 3.0mm and the minimum diameter was 10.7mm.
Plot the conventional stress-strain curve for the steel and determine the propotional limit, modulus of elasticity (i.e the slope of the initial part of the stress-strain curve), yield stress at 0.1% offset, ultimate stress, percent elongation in 50mm, and percent reduction area.

Fracture
In True stress-true-strain curve in tension of solid metal cylinder 45 mm high and 8 mm in diameter, two
pairs of values of stress and strain were given for the specimen metal after it had yielded (1) true stress =
217 MPa, and true strain = 0.35; and (2) true stress = 259 MPa, and true strain = 0.68. Based on these data
points, determine the following:
a) The average flow stress that the metal experiences if it is subjected to a stress that is equal to its
strength coefficient K.
b) The work done that the metal experiences if it is subjected to elongation in height of 45%
c) If during the deformation the relative speed = 20 mm/s, determine the strain rate at h = 50 mm and
h = 70 mm.
