英文摘要：

There exist phenomenon and mechanisms in multiple scales in metal plastic forming.Therefore,multiscale modeling ＆ simulation is a significant way to study the theory and techniques for integration of metal plastic forming and performance control.Herein,most important multiscale modeling methods recently proposed by international scholars are reviewed.Much more attentions are paid on the schematic for multiscale hierarchical modeling and the modeling approach for synchronous responses in multiple scales by coupling two or more multiscale models.The review will be worthy for reference in the work of multiscale modeling and simulation for the study of the integration theory of metal plastic forming and performance control.
