Beam Transverse Shear Stress Calculation

Beam Transverse Shear Stress Calculation

Beam Transverse Shear Stress Calculation

(OP)
Does anyone know where I can find documentation on how SOLIDWORKS calculates the transverse shear stress in beam elements. I am used to the tau=VQ/Ib formula.
SW appears to use a shear factor, but does not provide documentation on how the value is derived or used to calculate the maximum shear stress.

After playing with it, I figured out that the shear factor is just the ratio of tau_avg (V/A) to tau_max. So in a cylindrical cross-section beam, the shear factor using VQ/Ib would be 3/4 (0.75). When I let SW calculate the shear factor it produces 0.85723.

I assume the method SW uses produces more accurate results than VQ/Ib especially for "tricky" sections where VQ/Ib is not valid. I was however expecting the results to match for my simple circular rod.

Anyone have documentation on the calculation and applicability of this shear factor?

If the SW formulation is more accurate that the basic VQ/Ib, that's great. I would just like to understand how/why.
