Additive manufacturing technologies spread widely in multiple scientific sectors thanks to their flexibility and property customisation. However, many aspects must be studied further since multiple factors such as their microstructure and internal defects can drastically change the overall mechanical behaviour of the final products. In this work, the stress-strain behaviour of a Selective Laser Melting AlSi10Mg alloy is retrieved through a homogenisation approach with FEM analyses using the Representative Volume Element approach. To this purpose, an in-house code has been developed to model a random spatial pore distribution inside the RVE according to literature references and to impose the periodicity boundary conditions. Results are presented at different overall porosities.

Abstract
Additive manufacturing technologies spread widely in multiple scientific sectors thanks to their flexibility and property customisation. However, many aspects must be studied further since multiple factors such as their microstructure and internal defects can drastically change the overall mechanical behaviour of the final products. In this work, the stress-strain behaviour of a Selective Laser Melting AlSi10Mg alloy is retrieved through a homogenisation approach with FEM analyses using the Representative Volume Element approach. To this purpose, an in-house code has been developed to model a random spatial pore distribution inside the RVE according to literature references and to impose the periodicity boundary conditions. Results are presented at different overall porosities.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
