Eshelby-Kröner viscoelastic self-consistent model: Multi-scale behavior of polymer composites under creep loading

Résumé

The mechanical response of the composite structure in T650-35/PMR-15 aged at different temperatures was studied numerically. The time-dependent internal stresses in the composite ply and its constituents were computed during the creep process. In order to predict the effective properties of PMR-15/T650-35 composite ply in the temperature range [250-350°C], the time-dependent mechanical properties of PMR-15 matrix determined experimentally [1], were considered. The mechanical properties of the fibers do not experience any change due to the aging process in such a temperature range [2, 3]. In order to achieve the computations, the visco-elastic Eshelby Kröner self-consistent model was used.
