Abstract：

The composite cylinder SiCp/Al was investigated by 3D thermal-mechanical coupled simulation based on the finite element software Abaqus. The influences of the deformation parameters on damage field, strain field and temperature field during the upsetting process of composite cylinder SiCp/Al were analyzed, and the emergence of the drum-shaped area cracks was emphasized. The equivalent strain and load stroke of billet under different friction coefficients were carried out through data processing by Origin software, and their changing regularities were recorded. The results show that the amount of deformation has significant effect on the simulation results. When the deformation amount is 20% or 30%, the drum-shaped zone of forging has no cracks, and when the deformation amount increases to 40%, the drum-shaped zone cracks, but the friction coefficient has little effect on the temperature field and the damage field. With the increase of the friction coefficient, the center equivalent strain and load value increase too.
