摘要：
Additive manufacturing,as a representative of advanced manufacturing technology,has been widely used in aerospaceand other high-tech fields. Due to the complex processes of high energy density,extreme heating and cooling rates in metal additive manufacturing technology, the microstructure of additively manufactured as-built materials is often obviously different from that produced by traditionally manufactured technology,which has an important impact on the mechanical properties of metal materials. Crystal plasticity finite element method combines the crystal plasticity theory with the finite element method,which can research the relationship between the microstructure and mechanical properties of additively manufactured metallic materials across scales,and provide the strong support for the optimization of additive manufacturing processes. This paper first summarizes recent application of crystal plastic finite element method in metal additive manufacturing,and expounds the establishment method of geometric model,which can represent the microstructure characteristics of additively manufactured metallic materials,and the application of finite element method,finally points out the development trend. © 2024 Cailiao Daobaoshe/ Materials Review.
