Among the biocompatible materials, Ti6Al4V titanium alloy is widely spread due to its properties, such as corrosion and fatigue resistance combined with low density. can be processed by Additive Manufacturing technologies, Power Bed Fusion (PBF). The biomedical applications require good surface finishing ensure biocompatibility tissues organs. Machining an adequate process final roughness of co...

This study aimed to analyze the defects of large residual stress in laser additive manufacturing metal parts by establishing a milling numerical simulation Ti6Al4V titanium alloy thin-walled based on Johnson-Cook constitutive model alloy, modified Coulomb friction model, physical chip separation criterion and other theories, combined with finite element software ABAQUS. The influences depth, in...

Additive manufacturing (AM) has enabled the fabrication of complex geometries directly from design data and gained a lot interest. However, AM products can contain pores, which significantly reduce fatigue life. The main focus this work is to evaluate effect pores in Ti6Al4V dog-bone samples, produced by AM, propose methodology estimate life reduction due internal pores. bond-based Peridynamics...
