Abstract : In this paper, we present a statistical hyper-visco-elasto-plastic model comprising 7 characteristic parameters. To identify these parameters from material behavior, a campaign of experimental tests was under-taken at controlled temperatures (of -55 o C to +70 o C). These experimental tests were carried out on double-shearing test-piece constituted of a siliconed elastomer filled with silica subjected to triangular cyclic loading (at various deformation rates and various amplitudes) and in relaxation test at various levels of deformation. Finally, comparison of the model (thus identified) with experimental validation tests performed under multi-harmonic loading, shows the good representativeness of the model for a relatively wide frequency spectrum and a large field of deformation.
