Abstract

Abstract

The brain is the highest nerve center regulating physiological behaviors and functions. Brain tissue is a saturated porous material composed mainly of solid phase and liquid phase. Interactions between the solid phase, the liquid phase and the physiological environment (temperature in particular) are manifested in the coupled thermo-mechanical behaviors of brain tissue, and affected by internal temperature, seepage and stress fields. Characterization of the coupled thermo-mechanical behaviors of brain tissue is the key to understanding brain function and disease pathology. Firstly, the thermal and mechanical properties of brain tissue measured via different experimental methods were introduced, with a particular focus placed upon the effects of the strain rate and the temperature. Theoretical and numerical models describing the coupled thermo-mechanical behaviors of brain tissues were then summarized, including mechanical models, heat transfer models and coupled thermo-mechanical models. Finally, this important multidisciplinary field was summarized and prospected.
