Thanks to their particular mechanical properties, in particular their ability to undergo large deformations on the one hand, and to dissipate energy on the other hand, filled elastomers are used in many industrial fields and more particularly in that of transport. In service, most components are subjected to cyclic stresses and the loads are often multiaxial and non-relaxing. The optimization of such components in terms of service life requires the implementation of predictive tools to quantify their mechanical strength for these complex loads. On the other hand, their dissipative behavior associated with their low thermal conductivity leads to an accumulation of heat in the material leading to a rise in temperature during repeated loadings. We are talking about self-heating. Since this phenomenon tends to reduce the fatigue strength, it has been widely studied in recent years but rarely for multiaxial loadings. Finally, elastomers subjected to high temperatures for a certain time see their mechanical properties deteriorate. Studies that focus on this phenomenon called thermo-oxidative aging often focus on its impact on the fracture properties of the material and unfortunately neglect its impact on fatigue behavior.This thesis work consists in building a lifetime prediction tool based on the accumulation of damage taking into account both the multiaxiality of cyclic loadings, the phenomenon of self-heating as well as thermo-oxidative ageing

The objective of this study is to develop a model to reproduce the elastomer mechanical behaviour function of the temperature. For this study, preliminary experimental work is performed to highlight the different mechanical phenomena to present the material with changing temperature. The studied material is a fluoro-carbon synthetic elastomer (FKM), Viton. This elastomer has excellent performance at high temperatures and chemical attacks. Its properties are used for various applications such as sealing, damping, isolation, etc. The mechanical characterization of materials is performed using conventional tension, compression and relaxation tests on a range of temperatures from -40°C to 100°C. The cyclic loading tests reveal a significant presence of hyperelasticity for elastomers. The relaxation tests enable us to describe the viscosity of the material. In addition, loading tests interrupted by relaxations have also been carried out for different strain rates with relaxation times of 900s. They show equilibrium hysteresis demonstrating the presence of hysteresis for our material. In this study, we have chosen to consider only the temperature range from -8°C to 100°C to reproduce correctly the material behaviour. The model is a phenomenological constitutive model based on an additive decomposition of powers. The model consists of three stress contributions: hyperelasticity, viscosity and hysteresis. This model will be named Hyperelasto-visco-hysteresis (HVH) where the contribution is taken into account hyperelastic using phenomenological potential of Hart-Smith. The viscosity is described using the generalized Maxwell model and the hysteretic contribution is taken into account using an original model. In this study we consider only the first loading cycle of our material. A method of identification has been established to better take into account the different contributions of the model. The identification of material parameters for isotherms are performed in the range of temperature studied. Validation of the model will be initially tested at room temperature on a loading case of industrial gasket relaxation. To validate the model as a function of temperature we simulate different cases of loading isotherm. Then, the simulation of a relaxation test in compression undergoing temperature cycles is performed to compare the model to calculate temperature dependent
