Torsiuneelastic
Torsiuneelastic refers to the elastic component of a material’s or structure’s response when subjected to torsional loading. In this regime deformations are reversible and the shear stress–strain relationship is linear, so the material follows Hooke’s law for shear. The key quantity is the shear modulus G, which governs the stiffness to torsion.
For a solid circular shaft of radius R and length L carrying a constant torque T, the
For non-circular cross-sections, torsion involves warping and the relation between T and φ' is expressed through a
Torsiuneelastic is distinct from viscoelastic and plastic torsion. In the elastic regime, unloading recovers the original
