- Explain how does the term stress path as related to stress conditions in a soil mass?Tension specimens (diameter d0 0.500 in., gage length L0 2.00 in.) made of structural materials A and B are tested to failure in tension. (a) At failure the distances between the gage marks are LAf 2.90 in. and LBf 2.22 in.; the corresponding diameters at the failure cross sections are dAf 0.263 in. and dBf 0.471 in., respectively. Determine the percent elongation in 2 in. and the percent reduction in area for these two materials, and classify each material as either brittle or ductile. (b) From these tensile tests the following data are also obtained: EA 10.0 103 ksi, (Y)A 5 ksi, (U)A 13 ksi; EB 10.4 103 ksi, (Y)B 73 ksi, (U)B 83 ksi. From the data given here, make rough sketches (to scale) of the stress-strain diagrams of materials A and B.Define the term stress trajectories?
