Torsion of rods with elastic properties depending on the stress state type |

| Abstract |
Torsion problems for rods made of materials whose properties
change depending on the nature of loading or deformation are
stated. In these materials, processes of volume and shear
deformation are coupled, with the coupling parameters
depending on the loading nature. Such effects manifest
themselves in rocks, some sorts of structural graphite,
carbon-based composite materials, concrete, refractory ceramics,
as well as many other materials. It is shown that the classical
approach based on Saint-Venant's hypotheses as regards the
cross-section rotation and warping cannot be applied to
the materials in question, since in these materials, the displacements
due to torsion are coupled with those due to deformation
of the cross-section. Depending on the torsion conditions,
an axial compression force or a bending moment can appear.
Some of these effects are analyzed on the basis of the
approximate solution of the torsion problem for a rod with
rectangular cross-section. |
