中文摘要	To decrease thermal stress during laser metal deposition shaping (LMDS) process, it is of great importance to learn the transient thermal stress distribution regularities. Based on the "element life and death" technique of finite element analysis (FEA), a three-dimensional multi-track and multi-layer numerical simulation model for LMDS is developed with ANSYS parametric design language (APDL) for the first time, in which long-edge parallel reciprocating scanning paths is introduced. Through the model, detailed simulations of thermal stress during whole metal cladding process are conducted, the generation and distribution regularities of thermal stress are also discussed in detail. Using the same process parameters, the simulation results show good agreement with the features of samples which fabricated by LMDS.
