Experiments on the Mechanics of Rubber

III: Small Torsions of Stretched Prisms
  • A. N. Gent

A theorem, relating the torsional modulus for small torsions of a rod of incompressible highly elastic material, held in a state of simple extension, to the extension ratio and force necessary to maintain the extension, is verified experimentally for rods of vulcanized rubber of rectangular cross section.
