If the tensile specimen is not cylindrical rod shaped but a flat rectangular plate, how do
you expect necking to occur in this type of specimen?
Annealed low-carbon steel has a flow curve with strength coefficient = 80,000 lb/in2 and strain-hardening exponent = 0.25. A tensile test specimen with gage length = 2.0 in is stretched to a length = 3.5 in. Determine the flow stress and average flow stress that the metal experienced during this deformation.

- Two previously undeformed specimens of the same metal are to be plastically deformed by reducing their cross-sectional areas. One has a circular cross section, and the other is rectangular; during deformation the circular cross section is to remain circular, and the rectangular is to remain as such. Their original and deformed dimensions are as follows: Circular (diameter, mm) Rectangular (mm) Original dimensions 15.2 125 x 175 Deformed dimensions 11.4 75 x 200 Which of these specimens will be the hardest after plastic deformation, and why?arrow_forwardBriefly discuss the differences between the Engineering Stress versus Engineering Strain and the True Stress versus True Strain Diagrams for the test specimen. Briefly explain why the two plots are different.

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.arrow_forward
