The mechanical behavior of solid materials at nano/micrometer scale is increasingly concerned by researchers.Material properties are determined by the nonlinear coupling of different physical processes at micro-,meso- and macro-scales.Hence,the development of multi-scale simulation methods for nano/micro scale materials has been a hot topic of research.This paper reviews the advances of concurrent methods for multi-spatial scales and multi-temporal scales in recent years.The basic ideas,applications and disadvantages of these methods are introduced.The development,trend of multi-scale simulation methods are also given.
