| Abstract |
On the basis of elastic constitutive relations that reflect geometrically nonlinear second-order effects, we refine the theory of torsion of rectilinear rods of an arbitrary transverse cross-section. In particular, we obtain a universal formula, independent of the material properties, that determines the longitudinal strain arising as the rod undergoes free torsion. According to this formula, the length of a rod made of an isotropic perfectly elastic material can, in contrast to the traditional concepts, either increase or decrease as the rod undergoes torsion. Moreover, the variation in the length depends only on the geometry of the transverse cross-section. |
