集成计算材料工程在精确塑性成形中的应用现状与发展趋势

Integrated computational materials engineering(ICME), which might quantitatively describe material preparation, processing and service processes through modeling and calculation, was an advance and effective method to realize the precision plastic forming of materials under single or integrated fields such as mechanical loading, heating, electricity, magnetism, sound field etc. In recent years, ICME was widely used by researchers in precision plastic forming. The status, progresses and development trends of ICME in multi-scale modeling of plastic forming, buckling and fracture predictions were reviewed herein. Firstly, the applications of macroscopic, mesoscopic and microscopic modelling methods on precision plastic forming were systematically reviewed in precision plastic forming. The information transmission methods were analyzed among different scale models. Based on this, progresses of the prediction methods of the two main types of defects restricting precision plastic forming, buckling and ductile fracture using ICME were discussed. The accuracy of current main instability buckling and ductile fracture models was compared. Finally, the perspectives of the applications of ICME on precision plastic forming were presented.
