Question 15 (1 point) A material element is subjected to plane stress conditions. The stresses at the point of interest are as follows (units of MPa are assumed): 0x =-87 Oy =36 Txy =-77 Determine the normal strain in the z-direction, Ex, in microstrain (to one decimal place). So if the value is 18.4 E-06, just enter "18.4". You may assume Young's modulus is 72 GPa and Poisson's ratio is 0.3 for this material.
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. Calc...
