The Maximum Shear Stress theory (Tresca criterion) predicts yielding when the maximum shear stress equals:
(A) \sigma_y / 2
(B) \sigma_y
(C) \sigma_y / \sqrt{3}
(D) \sqrt{2} \sigma_y
Answer Key:
A
Step-by-Step Verified Solution
### Solution: Under uniaxial tension, au_{max} = \sigma_y / 2. Therefore Tresca predicts yielding when au_{max} reaches \sigma_y / 2. Correct: A.
