Static assessment of flawed thin AlSi10Mg parts produced by Laser Powder Bed Fusion

• Analysis of the static assessment thin and flawed AM parts made AlSi10Mg; Even if material is quasi brittle, fracture has to consider elasto-plastic behaviour. Flaw based on FAD adequate it allows obtain simple Limit Load Diagrams for determining acceptable flaws. Several factors must be considered within produced by Additive Manufacturing (AM) such as, example, heterogeneous microstructure, process-induced defects, surface quality, residual stresses, dependence material’s properties with building orientation. All these severely affect resistance fatigue loadings AMed components. Among possible failure mechanisms, promoted when cracks are present one most important conditions, in particular as-built parts, which might have reduced toughness ductility compared wrought alloy counterpart. In this work, we a comprehensive approach AlSi10Mg manufactured Laser Powder Bed Fusion. Two benchmark geometries were designed investigate typical geometrical features: i) walls tension ii) notched components bending. Finite Element analyses specimens showed that an elastic-plastic mechanics parameters needed correctly predict experimental failures, despite quasi-brittle behaviour shown alloy. view results, paper explores applicability Failure Assessment Diagram (FAD), tool used conventional ductile materials, parts. The results show makes properly failures specimens.
