摘　　要：以耦合的方式来处理体积成形过程中塑性变形和温度场之间的相互影响和相互作用 ,开发了一套能进行热力耦合分析的刚塑性 /刚粘塑性有限元模拟软件HFORGE2D ,并利用该软件对镦粗过程和模锻过程进行了数值模拟 。For treating the interaction between plastic deformation and temperature field in a coupled manner during the bulk metal forming process, a computer program HFORGE2D,which is based on the rigid visco\|plastic finite element method and has the capability to carry out a coupled thermal\|mechanical analysis, was developed.And then,it was used to simulate the processes of upsetting and die forging respectively to reveal the relationship between deformation and temperature.
