Mandrel forging process simulation of thick wall tube

摘要：

By means of finite element method,the mandrel forging process was simulated.It is concluded that (1) the changes of the temperatures,stresses and strains at the different regions of thick wall tube were simulated during the mandrel forging process,(2) based on the temperature,stress and damage distributions of the forged tube,the forming defects analyze was proceeded and it is concluded that cracks may occur near the head surface or around the side edge during the plastic deformation process.
