WebAccording to Wahl, Maximum shear stress is given by, Maximum shear stress = Wahl’s Factor is given by, Wahl’s Factor , 17.5.2 Deflection in Helical Springs If J is polar moment of inertia and G is Modulus of Rigidity of coil, angular deflection of the wire due to twisting is given by, References Design of Machine Elements by VB Bhandari WebMaximum 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.
