A Review of Metal Additive Manufacturing Application and Numerical Simulation

Metal additive manufacturing has achieved high economic benefits in aerospace, military, biomedical and other high value-added industries. It has good application prospects in automobile, nuclear power, petrochemical, ship and other traditional industries. The numerical simulation can effectively predict the thermal evolution, molten pool morphology, residual stress and deformation in the process of adding metal. However, due to the limitation of the calculation speed of commercial software such as ANSYS and ABAQUS, the calculation results are difficult to accurately guide the actual manufacturing process of adding metal components. Therefore, special simulation software for additive manufacturing should be developed to carry out simulation and prediction. (paper)
