i am new to doing tensile test and i have a simple question
i am testing some aluminum samples of 2024-T851 and 7075-T6 and i read the ASTM E 8 Standard for tensile testing it doesn't specifally mention the cross head speed for testing different material and i was wondering what rate to use? and i was thiking for a strain rate of 0.05 in.in./min.
i am using an MTS test machine using a 20KN load range and a 1 in. MTS extensometer mine a round bar with 0.25 in. diameter.
