A steel with a yield stress of 300 MPa is tested under a state of stress whereσ2 = σ1/2 and σ3 = 0. What is the stress at which yielding occurs if it isassumed that:(a) The maximum-normal-stress criterion holds?(b) The maximum-shear-stress criterion holds?(c) The distortion-energy criterion holds?
(SI Units) In a tensile test on a steel specimen, true strain = 0.11 at a stress of 245 MPa. When true stress = 340 MPa, true strain = 0.31. Determine the strength coefficient and the strain-hardening exponent in the flow curve equation.
For a certain high-temperature alloy, failure was reported after 4100 hrs at 680°C when subjected to a stress level of 270 MPa. If the same stress were applied at 725°C, how long would the sample be expected to last? State any assumptions you must make to allow you to make this determination.
For a certain metal the strength coefficient K = 600 MPa and the strain hardening exponent n =0.20. During a forming operation, the final true strain that the metal experiences ε = 0.73.Determine the flow stress at this strain and the average flow stress that the metal experiencedduring the operation.
As the tempering temperature of a heat treated steel increases the associated values of Brinnell hardness also increase, while the values of tensile strength and yield strength decrease. True or false
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.

Tensile and fully reversed loading fatigue tests were conducted for a certain steel alloy and revealed the tensile strength and endurance limit to be 1200 and 550 MPa, respectively. If a rod of this material supply were subjected to a static stress of 600 MPa and oscillating stresses whose total range was 700 MPa, would you expect the rod to fail by fatigue processes? Hint: You may want to plot a diagram to aid in presenting your answer.
A 50 mmm long circular rod of the AISI 1015 hot rolled steel with a diameter of 12.5 mm is loaded in tension to failure. From the test it is learnt that the yield strength = 315 MPa, the tensile strength = 420 MPa, the elongation at fracture = 39% and the reduction in area = 51%. It is also observed that 45% of the total elongation was uniform in nature prior to the onset of necking. a) What is the true strain at fracture? b) Calculate the true stress at the point of onset of plastic instability c) What is the the strength coefficient K for this steel?

From the work of D. C. Jillson, Trans. AIME 188, 1129 (1950), the following data were taken relating to the deformation of zinc single crystals.
