要約

Filled elastomers (rubbers) are composite materials distinguished by the complex structure and specific properties due to the interaction of the filler and binder at the phase interface. A structural-phenomenological model of the viscoelastic behavior of rubber is suggested in the present work. Apart from the plastic, elastic, and viscous elements, the model involves a new type of elements − transmission ones that connect the structural deformations of the matrix at the nanolevel with the deformation of the material. A comparison with the experiment has demonstrated a good reproducibility of the Mullins softening effect and the viscoelastic behavior of rubber in a wide range of the amplitudes of deformation. The determination of the unknown constants of the model is split into several independent stages, which substantially simplifies practical realization.
