低维纳米复合材料多场耦合力学研究进展

Low-dimensional nanocomposites have attracted significant attention in the area of solid-state battery and aerospace engineering, due to their superior mechanical properties while maintaining lightweight. The mechanical behaviors of low-dimensional nanocomposites are characterized by the multi-field coupling and multi-scale features while operating under complex environments in practical applications. In this research, the multi-field coupled mechanics of low-dimensional nanocomposites are systematically reviewed from the experimental, theoretical, and numerical aspects. The recent progress can be divided into three parts: grain size dependent elastoplasticity, temperature-dependent viscoelasticity, and temperature-dependent viscoplasticity. Microscopic characteristics, such as temperature effects, dislocation, interface effect and microstructural evolution, are connected with the macroscopic multi-field coupled behaviors via the multi-scale models. Finally, the existing issues and prospectives in the research of multi-field coupled mechanics of low-dimensional nanocomposites are summarized.
