摘　　要：界面是复合材料/结构的重要组成部分和薄弱环节,其力学性能对复合材料/结构的整体力学行为和功能具有重要影响。唯象学的界面本构关系在求解各类含界面的材料和结构问题中发挥了重要作用,但其忽略了细观尺度上复杂的损伤失效过程。随着多相粘结剂的发展和应用,界面多尺度模拟领域取得了重要进展。本文首先对界面进行分类,其次阐述界面多尺度模拟的基本问题,然后总结界面多尺度模拟方法和界面均匀化中的几个关键问题;接着分别综述界面单向多尺度和双向多尺度研究相关进展,最后对界面多尺度力学需要进一步研究的问题进行展望。The interface is an important component and a weak link of composite materials/structures,and its mechanical properties have an important influence on the overall mechanical behaviors and functions of composites.Phenomenological interfacial constitutive laws have played an important role in solving various problems of materials and structures with interfaces,but they neglect the complex damage and failure processes at the mesoscopic scale.With the development and application of multiphase binders,important progress has been made in the field of multi-scale modeling and analysis of the interface.Firstly,interfaces are classified based on their geometrical configurations.Then,the fundamental problems of interface multiscale modeling are clarified,and modeling methods and key issues in interface multiscale modeling are summarized.Research progresses in both one-way and two-way multiscale modeling of the interface are reviewed.Finally,the problems that need to be further studied in interface multiscale modeling are prospected.
