Retrospect and Prospect of Numerical Simulation Research for Large Forging Processes--commemoration of twentieth anniversary of "Heavy Casting and Forging"

The research development of ingot solidification,FEM analysis for forging process, moire.phase transformation and numerical simulation for heat treatment in mechanical Engineering Department of Tsinghua University. was reviewed in this paper. Application of the research results above to the design of heavy forging processes,and softwares developed by the authors were also introduced. Finally,the authors prospected the trends of numerical simulation technique research for heavy forging processes in future.
