- 1 15 Points Aluminum Alloy 2024 T4 Of Table 9 1 Will Be Subjected In Service To A Stress Amplitude A 150 Mpa And A 1 (22.03 KiB) Viewed 63 times
1. (15 points) Aluminum alloy 2024-T4 of Table 9.1 will be subjected in service to a stress amplitude a = 150 MPa and a mean stress Om = 120 MPa. A service life of 12,000 cycles is desired. What are the safety factors in stress (XS) and life (XN)? For this aluminum alloy, use the SWT mean stress equation (Eqn. 9.18) to compute the in-service equivalent completely reversed stress amplitude, Oar.
