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 |
