The image above represents critical shear stress. To calculate critical shear stress, two essential parameters are needed and these parameters are Stress (σ) and (cosφcosλ)max.
The formula for calculating critical shear stress:
τR(max) = σ(cosφcosλ)max
Where:
τR(max) = Critical Shear Stress
σ = Stress
φ, λ = Stress Axis Orientation
Given an example;
Find the critical shear stress when the stress is 14 and the (cosφcosλ)max is 2.
This implies that;
σ = Stress = 14
(cosφcosλ)max = 2
τR(max) = σ(cosφcosλ)max
So, τR(max) = (14)(2)
τR(max) = 28
Therefore, the critical shear stress is 28 Pa.
