The homogenous state of stress for a metal part undergoing plastic deformation is
T = 
5 10 0 
5 10 0 5 10 0
Where the stress component values are in MPa. Using Von Mises yield criterion, the value of estimated shear yield stress, in MPa is
-
- 9.50
- 16.07
- 28.52
- 49.41
Correct Option: B
σeq = √1/2{(σ11 - σ22)² + (σ11 - σ22)² + 6[σ²12 + σ²23 + σ²13]}
We know, σ11 = 10, σ22 = 20,
σ33 = – 10;
σ12 = 5;
σ23 = σ13 = 0
∴ σeq = 27.839 MPa
Shear stress at yield, τy = σeq/√3
= 16.07 MPa
