Abstract: Conventionally, additive manufacturing (AM) methods such as Direct Energy Deposition (DED) and Laser Powder Bed Fusion (LPBF) has been mainly adopted to produce complex designs. In recent times, site-specific AM properties can be produced by adopting a bidirectional scanning strategy to produce near-perfect single crystals through epitaxial grain growth. In this study, various site-specific dogbone models’ mechanical behaviour is observed using finite element analysis. The effects on von-Mises stress concentrations at various equivalent plastic strain (PEEQ) levels were analysed by experimenting with various geometric designs and texture orientation. Simulation results demonstrated that site-specific AM textures' tensile strength has a strong dependency on the orientation of textures to the applied load.
