Viscoplasticity of elastomeric materials: experimental facts and constitutive modelling

摘要

A characteristic of filled elastomers is their ability to undergo very large deforma- tions without damaging their internal structure. The material behaviour is mainly elastic, however, elastomers show hysteresis effects leading to damping properties, which are quite important as regards their applications in various fields of mechanical engineering. A series of experiments (tension, torsion and combinations of both) was carried out on Cylindrical bars made of a carbon-black filled rubber mixture.
