摘要
综述了金属轧制过程中裂纹演变塑性有限元模拟的研究进展。介绍了刚塑性有限元和弹塑性有限元的原理;着重介绍了轧制中轧件边角部裂纹、轧件表面裂纹和轧件内部裂纹的有限元模拟国内外最新理论和应用进展,并总结了国内外的研究特点;最后展望了塑性有限元未来发展趋势。
The recent research progress of microstructure evolution simulation in metal rolling process with plastic finite element method is introduced.The rigid-plastic FEM and elastic-plastic FEM theory are introduced.The recent new theory and research progress of the corner crack evolution,surface crack evolution and inner crack evolution simulation in metal rolling process with plastic finite element method are emphatically introduced at home and abroad.And the research characteristics of them are summarized.Finally,the future development trend of the plastic FEM is introduced.
