Assume a factor of safety of 3.0, data in Figure 8.20 were taken for reversed axial tension-compression tests, and that S is stress amplitude. Procedures to conduct a Uniaxial tension test: Make sure you zero out the vernier calipers. Once calipers have been zeroed out, get a reading on the diameter of the test samples (make sure you are below the filet but still close to the end of the tensile specimens). Once a reading has been taken turn the calipers 90 degrees at the same place .
