In particular, the results from the torsion test will be compared to the results of the engineering tensile test for a particular alloy using the effective stress-effective strain concept. EQUIPMENT • Constant-diameter gage section torsion specimen of 6061-T6 aluminum • Torsion test machine with grips, troptometer, and force sensor. PROCEDURE2. Press the ‘Peak Hold’ button of the Load Meter so that it records the maximum torque in the test. 3. For the first part of the test the specimen will be stressed in its elastic region, so you must increase the angle of twist in small steps of 1 degree. 4. At each angle, record the angle and torque value. 5.
