Torsionslast
Torsionslast, or torsional load, is a mechanical load that causes a body to experience torque about its longitudinal axis. This type of loading induces shear stresses that vary over the cross-section and produces an angular deformation or twist. Torsionslast is common in rotating components such as shafts and axles, as well as in structures or fasteners subjected to twisting torques.
For circular shafts under pure torsion, the shear stress at a distance r from the center is
In design and analysis, torsionslast is treated alongside material strength, fatigue behavior, and potential interactions with
Measurement and testing commonly involve torsion tests that record torque and resulting angle of twist to
