Answer:
Applied Stress > 58.29 MPa
Explanation:
- Resolved shear stress should be greater than critically resolved shear stress in order to cause the single crystal to yield
Given angles are
∅ = 42.7 degree
Ф = 48.3 degree
Critically resolved shear stress = 28.5 MPa
If we consider
Critically resolved shear stress = resolved shear stress
Applied stress can be found by
(1)
Applied Stress =
Applied Stress =
Applied Stress = 58.29 MPa
We got reference
- By putting applied stress values of greater than 58.29 MPa in equation 1 we get
Resolved Shear Stress = 60 x Cos(48.3) x Cos(42.7)
Resolved Shear Stress = 29.33 MPa
Therefore, by the above calculation we conclude that applied stress should be greater than 58.29 MPa, In order to make resolved shear stress to be greater than critically resolved shear stress that is essential for single crystal to yield.
