In summary, SOLIDWORKS Simulation uses a general and conservative method to calculate the "Constant for maximum shear stress calculation (CTOR)" value of beam element cross sections. By comparison, text books typically devise special formulas for each cross section that they study. Therefore, the τmax value given by SOLIDWORKS Simulation will always be greater than either the prediction made by the textbooks (Roark's Formulas for Stress and Strain, for instance) or values obtained from SOLIDWORKS Simulation for the same analysis using solid elements.
