Material models and mechanical properties of titanium alloys produced by selective laser melting

Modeling of additively manufactured titanium alloys behavior in loading conditions represents a step forward to understand its advantageous and favorable properties in various applications, such as medical implants, components for aerospace, automotive and process industry. The knowledge on their behavior is still very limited, especially if the focus is directed to modeling of the behavior of titanium alloys produced by selective laser melting (SLM), which opens many possibilities in achieving optimal design of titanium alloy components. Therefore, an overview of the selected properties of these materials has been detailed, in order to choose or develop appropriate material models suitable for their behavior modeling. By adapting existing or developing new constitutive material models, in further work the behavior of SLM antibacterial Ti- xCu titanium alloys will be modeled considering their microstructure and defects. In this study, state-of-the-art on mechanical properties of AM Ti6Al4V alloy is given, as well as Ramberg – Osgood (R – O) parameters for modeling of monotonic and cyclic elastoplastic behavior.
