Torsion in thin-walled members refers to the twisting or rotational deformation of a structural member due to an applied torque or twisting force.
Thin-walled members such as beams, columns, and tubes with a relatively small cross-sectional area compared to their length are more susceptible to torsion.
Torsion can significantly reduce the strength of a thin-walled member, especially if the applied torque exceeds the member's torsional capacity. This can lead to buckling, deformation, or failure of the member.
Torsion can be prevented by ensuring the structural member is designed with sufficient stiffness and strength to resist the applied torque. This can be achieved through proper material selection and cross-sectional shape design.
The most common methods for analyzing torsion in thin-walled members include the Saint-Venant's torsion theory, the thin-walled beam theory, and the finite element method. These methods take into account factors such as shear stress, warping, and stress concentrations to accurately predict the behavior of the member under torsion.
