Énergie volumique de déformation du caoutchouc vulcanisé et renforcé au noir de carbone pour des applications industrielles

Abstract

Abstract The hyperelastic behavior of rubber-like materials can be derived from the strain energy density function W which is determined from experimental results obtained in homogeneous strain, such as uniaxial tension, pure shear and equibiaxial tension. In the particular case of carbon filled reinforced rubber, the shape of the W function can be identified from a minimum number of experimental tests. The form of the W function has been proposed in the literature only for large strain domain. We present in this paper a new strain energy density function W for carbon black reinforced rubber which can predict the mechanical behavior of the material at small and large strain.
