Abstract: The thermal-mechanical coupling behaviors of materials and structures under high temperature and highspeed impact complex conditions are closely related to the structural safety and service life of key astronautic and aeronautic armaments such as hypersonic vehicles. How to achieve an accurate characterization of complex thermal-mechanical properties of material structures has long been of great concern to researchers and engineers in industry. Currently, numerous experimental testing techniques and characterization methods have been developed, which provide important technical support for material selection, structural design, safety verification and behavior prediction of key components. In this review, the thermal-mechanical response of material structures under extreme conditions of highspeed impact and high temperature is outlined. The technical characteristics and field of application of classical dynamic/high temperature mechanical properties testing methods based on the uniform state assumption are systematically summarized. Meanwhile, a variety of rapidly developing full-field measurement techniques, high-speed imaging techniques and inverse parameter identification strategies are introduced. The current application status of the full-field measurement based inverse identification methods for dynamic/high-temperature mechanical properties is highlighted. Practical application examples of the material thermo-mechanical parameters identification in the FEM prediction of mechanical behavior and structural improvement of armament components under extreme operating conditions are presented. Finally, the prospective development trend of the advanced testing methods for thermal-mechanical properties of materials under complex conditions are discussed.
