| Abstract: | The phenomena of linking length scales and multi-levels as well as the related multi-scale coupling reflect the basic nature of matter world and intrinsic character of multi-discipline cross.There will be great theory and engineering significance for introducing multi-scale coupling into the simulation of material design and processing.This paper dresses the issues on the length and time,multi-scale characteristics of material science and related methods in each scale as well as the basic ideology of erecting multi-scale modeling,pointing out the foreground of introducing multi-scale methods into advanced polymer processing.Two-scale coupling model of injection for short fiber reinforced composite materials is introduced as a illustration as well. |
