AbstractIn order to improve that quality of sample and decrease the stress during process, it is of great importance to study the residual stress distribution during direct laser metal deposition (LMDS) process. In this paper, according to the "element life and death" technique of finite element method, with APDL, we simulated the effects of long edge reciprocating scanning method, short edge reciprocating scanning method and direction orthogonal changing in different layers reciprocating scanning method to residual stress distribution during whole LMDS process are studied. The residual stress distribution under different scanning methods is researched in detail. Using the same process parameters, the simulation result show good agreement with the features of sample which fabricated by LMDS.
