Torsion (mechanics) - Wikipedia
In the field of solid mechanics, torsion is the twisting of an object due to an applied torque [1][2]. Torsion could be defined as strain [3][4] or angular deformation [5], and is measured by the angle a chosen section is rotated from its equilibrium position [6].
Torsion • Torsion refers to the twisting of a structural member when it is loaded by couples that produce rotation about the longitudinal axis • The couples that cause the tension are called Torques, Twisting Couples or Twisting Moments
Understanding Torsion - The Efficient Engineer
2023年2月19日 · The video below takes an in-depth look at torsion, including how to calculate the angle of twist, and the shear stresses and shear strains associated with torsional deformation. It also covers how ductile and brittle materials fail under torsional loads.
Mechanics of Materials: Torsion - Boston University
Unlike axial loads which produce a uniform, or average, stress over the cross section of the object, a torque creates a distribution of stress over the cross section. To keep things simple, we're going to focus on structures with a circular cross section, often called rods or shafts.

2021年9月2日 · The strain energy per unit volume in a material subjected to elastic shearing stresses \(\tau\) and strains \(\gamma\) arising from simple torsion is: \[U^* = \int \tau d\gamma = \dfrac{1}{2} \tau \gamma = \dfrac{\tau^2}{2G} = \dfrac{1}{2G} (\dfrac{Tr}{J})^2\nonumber\]

Circular shaft experiencing an axial torque. A solid, circular cross-sectioned shaft experiences an axial torque T, as shown above. The hypothesis used in developing the stress and strain in the shaft is that all points on a cross-section of the shaft experience the same angle of twist.
