The uniaxial yield stress of a material is 300 MPa. According to Von Mises criterion, the shear yield stress (in MPa) of the material is _______.
-
- 173.28
- 172.28
- 171.28
- 169.28
Correct Option: A
If there is uniaxial loading yield stress is σy
As per Von Mises failure theory
σ²y = σ²1 + σ1σ2 + σ²2
Under pure shear stress loading
σ1 = – σ2 = τ
then σ²y = τ² + τ² + τ² = 3τ²
| ⇒ τ = | √3 |
| Hence τ = | = 0.5577σy = 173.28 | √3 |
Where τ is shear yield stress
