WebbMaximum Shear Stress The maximum shear stress at any point is easy to calculate from the principal stresses. It is simply \[ \tau_{max} = {\sigma_{max} - \sigma_{min} \over 2} \] This applies in both 2-D and 3-D. The maximum shear always occurs in a coordinate system orientation that is rotated 45° from the principal coordinate system.
