Simulation of 1.2765 DIN steel billet and crack analysis during the forging process using DEFORM 3D softwareSimulation des Stahlrohlings aus dem DIN-Werkstoff 1.2765 und der Rissanalyse wahrend des Schmiedeprozesses mittels DEFORM 3D Software

The plastic deformation behavior of 1.2765 DIN steel during forging process and the feasibility of simulation in the forging of 1.2765 DIN steel at four different temperatures has investigated by using professional plastic distorting software DEFORM 3D v11.0. Additionally, the total load, effective stress, effective strain, and total velocity at four different points of the billet material has been simulated during the upsetting process. The main finding of this study are as follows: 1) during the forging process, the coefficient of friction between the die and the specimen has been influenced more on the flow stress of the material. 2) Effective strain at side edges of the specimen has reduced due to lower recrystallization temperature. 3) Velocity of the particle at side edges has been more due to the unrestricted movement of particles during the forging process. It has also concluded that the particles located at side edges, faces, and near to the top head of the specimen were exceeding stress value compared to allowable stress.

Automated summary

The study found that the coefficient of friction between the die and the specimen had a significant influence on the flow stress of the material during the forging process. Additionally, the effective strain at the side edges of the specimen decreased due to a lower recrystallization temperature, while the velocity of particles at the side edges increased because of unrestricted movement during forging. It was also concluded that particles located at the side edges, faces, and near the top head of the specimen experienced stress values exceeding the allowable stress.
