Abstract Modeling of ad itively manufactured titanium alloys behavior in loading conditions represents s ep forward to understand its dvantageous and favorable p operties in various applications, such as medical implant , components r aerospace, automotiv a d proc ss industry. The knowledge on their behavior is still very li ited, especially if the focu is directed to modeling of the behavior of tita ium alloys produced by selective las r melti g (SLM), which op ns many possibilities in achi ving optimal design of titanium alloy compon nts. Theref re, an overv ew of the elected prop rties of these materials has been deta led, in order t choose or develop approp i te material models suitable for their behavior modeling. By adapting ex sting or deve oping new constitutive mater al models, in further work the be avior of SLM antibacterial Ti-xCu tit nium alloy will be modeled considering their micro tructur and defects. In this study, state-of-the-art o mecha ical properties of AM Ti6Al4V alloy is given, as well as Ramberg – Osgood (R – O) parameters for modeling of monotonic and cyclic elastoplastic behavior. © 2021 The Authors.

Mažurani ć 2, Slavonski Brod 35000, Croatia Abstract 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. 4th International Conference on Structural Integrity and Durability, ICSID 2020 Material models and mechanical properties of titanium alloys produced by selective laser melting David Liović a , Marina Franulović a, *, Dražan Kozak b a University of Rijeka - Faculty of Engineering, Vukova ska 58, Rijeka 51000, Croati b J.J.
