This contribution deals with the experimental investigation of cables showing inelastic behavior under bending deformation. A new experimental device, which enables the direct measurement of the quantities entering the constitutive law for bending, i.e. the bending moment and bending curvature, is introduced. Results from advanced cyclic experiments executed on this new pure bending device show inelastic effects. It is remarkable, that this procedure allows for the distinction of intrinsic inelastic effects, e.g. due to friction between the constituents, from global inelastic effects such as damage of the specimen.
