A 2024-T3 aluminum alloy smooth bar has a diameter of 10 mm and is subjected to a constant amplitude cyclic bending with R -0.2. For the material, assume the following properties: Su = 469 MPa, Sy 379 MPa, S'y = 427 MPa, S(at 5x10% cycles) = 138 MPa. The component (beam) is to be designed for a life of 50,000 cycles. Using appropriate approximate models, a. Determine the maximum bending moment Mmax (for 50,000 cycles). b. Check if this design is safe against failure by yielding. %3D %3D %3D %3D
