High cycle fatigue life estimation of AlSi10Mg processed by laser powder bed fusion
Hovig, Even Wilberg; S. Azar, Amin; Sunding, Martin Fleissner; Sørby, Knut; M'hamdi, Mohammed; Andreassen, Erik (Journal article; Peer reviewed, 2018)Fatigue life is known to be dependent on the surface properties of the material. Surface roughness provokes local stress concentration and cause crack initiation even at minute cyclic loads. In laser powder bed fusion, the ... -
High cycle fatigue life estimation of materials processed by laser powder bed fusion
Hovig, Even Wilberg; S. Azar, Amin; Sunding, Martin Fleissner; Andreassen, Erik; Sørby, Knut (Journal article, 2019)The fatigue life of metal components is known to depend on the surface topography. For components made by laser powder bed fusion, the roughness of the as‐built surfaces depends on the orientation of the component surface ... -
