Article
Accés obertResidual stresses and distortion in Additive Manufactured (AM) parts are two key obstacles which seriously hinder the wide application of this technology. Nowadays, understanding the thermomechanical behavior induced by ... -
Smart-substrate: a novel structural design to avert residual stress accretion in directed energy deposition additive manufacturing
Lu, Xufei; Zhang, Guohao; Chiumenti, Michele; Cervera Ruiz, Miguel; Slimani, Mehdi; Ma, Liang; Wei, Lei; Lin, Xin (Taylor & Francis Group, 2023-01)
Article
Accés obertResidual stresses, related distortions and cracks are detrimental in metallic Additive Manufacturing (AM). Previously developed stress-control strategies based on reducing thermal gradients hardly diminish the stress ... -

Article
Accés obertThis paper proposes a strategy to optimize the design of the substrate structures used in Additive Manufacturing (AM) by Directed Energy Deposition (DED) to minimize the residual stresses induced by this fabrication process. ... -
Thermo-mechanical simulation of annealing heat treatment of Ni-based GH4099 superalloy made by laser powder bed fusion
Lu, Xufei; Chen, Chaoyue; Zhang, Guohao; Chiumenti, Michele; Cervera Ruiz, Miguel; Yin, Haoliang; Ma, Liang; Lin, Xin (Elsevier, 2023-07)
Article
Accés restringit per política de l'editorialLaser powder bed fusion (LPBF) additive manufacturing (AM) unavoidably generates residual stresses due to sharp thermal gradients and the strong mechanical constraints of the substrate. These stresses can lead to large ...
