The model shows a cantilever that is restrained on one side, with an I-section cross-section. The warping is restrained at the support. A torsional moment of 10 kNm acts on the free end. The calculation is performed using the Torsional Warping (7 DOF) add-on.
Warping is restrained at the fixed end. The primary torsional moment, Mt,pri, is zero there, and the entire torsional moment is transferred as a secondary torsional moment, Mt,sec, via Warping Torsion. The warping bimoment, Mω, reaches its maximum value of 15.70 kNm² at this point. Toward the free end, St. Venant torsion accounts for the majority (Mt,pri = 9.16 kNm, Mt,sec = 0.84 kNm). At every point, the sum of Mt,pri and Mt,sec yields the applied torsional moment of 10 kNm.
