Abstract Residual stresses and deformations are one of the challenges needs to solve for metal additive
manufacturing part. Finite element method plays an important role in predicting the residual stresses and
deformations to reduce the experimental costs, and provides a powerful tool for the optimization of process
parameters and scanning strategies of heat source. However, the key problem in simulation is the mismatch
between the melt pool and the built part in both spatial and temporal scale. This would result in large
discretization in both spatial and temporal domains in the simulation, which gives rise to huge
computational cost. Therefore, it… More >
