Question

The measured strains are ε,-8001s, eb--420 μs and ε.-640 μs. The material is Al 2024-T4 aluminium alloy. (a) Determine the strains in x-y axes (Ex, Ey and Yxy) and show them in deformed element. Calculate the stresses by using material properties given in the Table. (b) Determine the stresses for the oriented element in 0 30° from the original position in the counter clockwise direction by using Mohr circle and represent the stress state. 60° 60 Young's Modulus (GPa) 73 Matera Yield Stress Ultimate Stress Y PoissonDensity Ratio kg/m3 0.332780 (MPa) 324 (MPa) 469 Al 2024-T4
