The image of yield stress for single crystal is represented below. To calculate yield stress for single crystal, two essential parameters are needed and these parameters are Critical Resolved Shear Stress (τcrss) and (cosφcosλ)max.
The formula for calculating yield stress for single crystal:
σy = τcrss/(cosφcosλ)max
Where:
σy = Yield Stress for Single Crystal
τcrss = Critical Resolved Shear Stress
φ, λ = Stress Axis Orientations
Given an example;
Find the yield stress for single crystal when the critical resolved shear stress is 24 and the (cosφcosλ)max is 8.
This implies that;
τcrss = Critical Resolved Shear Stress = 24
(cosφcosλ)max = 8
σy = τcrss/(cosφcosλ)max
That is, σy = 24/8
σy = 3
Therefore, the yield stress for single crystal is 3 Pa.

Calculating the Critical Resolved Shear Stress when the Yield Stress for Single Crystal and the (cosφcosλ)max are Given
τcrss = σy x (cosφcosλ)max
Where:
τcrss = Critical Resolved Shear Stress
σy = Yield Stress for Single Crystal
φ, λ = Stress Axis Orientations
Let’s solve an example;
Find the critical resolved shear stress when the yield stress for single crystal is 20 and the (cosφcosλ)max is 4.
This implies that;

σy = Yield Stress for Single Crystal = 20
(cosφcosλ)max = 4
τcrss = σy x (cosφcosλ)max
So, τcrss = 20 x 4
τcrss = 80
Therefore, the critical resolved shear stress is 80.
