Question

Problem 2. A dogbone tension specimen of a material is shown in figure. Longitudinal position and force data from a tension test on the sample is shown in table 1. Create a longitudinal stress- strain curve of the material. AB in the figure shows the gauge length which is equal to 10.97 mm. The width and thickness in the gauge area are 3.18 mm and 1.863 mm, respectively. Table 1 Gauge Width Thickness length (mm) (mm) )m) Tension(V) Strain Stress(Mpa 3 180 1863 93 3300086 oo00 0000 323 330 9296 0003 1555 420 330 39 628 515 33070 983 606 000 101.535 682 670 121.634
