The project aims at a aerospace fiber metal laminates(FMLs), and the thermal contact resistance, temperature, displacement and stress distributions as well as dynamic response of such a structure are systematically studied, then high temperature resistance and thermoelatoplastic dynamic response are characterized, finally the bidirectional feedback mechanism of three dimensional heat transfer behavior and thermodynamic response for the FMLs structure with interlaminar thermal contact resistance effect are studied.. The innovations of this project include: In view of the solid-liquid-vapor multiphase phase change process for the aerospace FMLs structure under three dimensional hot environment, a new three dimensional heat transfer model based on phase change process is established; Based on series connection for thermal contact resistance and thermal transfer of the FMLs structure between layers, a novel heat transfer network model including interlayer thermal contact resistance is established; bidirectional feedback mechanism of thermodynamic response for structure between thermal contact resistance, temperature and corresponding thermoelatoplastic dynamic response are set up.. This project intends to explore the effect of hot environment factors, external load and structural parameters on response mechanism of the thermal contact resistance, temperature, displacement and stress fields for the FMLs structure, which is of important theoretical guiding significance and engineering application value for deep understanding the “bidirectional feedback mechanism research of thermodynamic response for a FMLs structure with interlaminar thermal contact resistance” under three dimensional hot environments.
