In the context of passive damping, various mechanical systems from the space, aeronautic or auto-mobile industry use elastomer components (shock absorbers, silent blocks, flexible joints...).These materials have frequency, temperature and amplitude dependentcharacteristics. The associated numerical models may become computationally too expensive during an optimization process.The aim of this work is to propose an efficient reduced model of rubber devices that account for the viscoelastic damping and the non-linear pre-stress in the dampers.The first part of this thesis is about how to include the viscoelasticdamping in the reduced model. It starts by using a viscoelastic constitutive relation, based on experimental identification, within th...
