The twist or deformation of a body set up by a torque.
Torsion Theories
- Saint Venant torsion theory - basic torsion theory for which warping is not restrained
- Vlasov torsion theory - more general torsion theory for which warping can be restrained
Notation
The following notation is used throughout the torsion topic, unless noted otherwise:
- ... bimoment
- ... sectorial moment of inertia
- ... angle of rotation due to torsional moment
- ... first derivative of with respect to the local X axis of the member
- ... second derivative of with respect to the local X axis of the member
- ... third derivative of with respect to the local X axis of the member
