Using the software MARC/AutoForge3.1, a three-dimensional thermo-mechanical coupled elasto-plastic Minite Element Method (FEM) was used for simulation of a two-pass tube tension-reducing process of 33Mn2V steel for oil well tubes.

• 利用MARC/AutoForge3.；1元件；使用三维弹塑性热力耦合有限元方法模拟采用新型油井管用钢33Mn2V热轧制管的双道次张力减径过程；并直观地显示了三维管件材料内部和表面不同方位的金属流动、应力、应变和温度演化情况
