Elastic and failure response of imperfect three-dimensional metallic lattices: the role of geometric defects induced by Selective Laser Melting (2017, background): “Metallic cellular materials can be designed to offer unique combinations of mechanical and physical properties, often unachievable with fully dense metals ( Wadley, 2006 ; Evans et al., 1998 ; Cabras and Brun, 2016 ).”
Design and Optimization of Lattice Structures: A Review (2020, background): “However, it still needs severe deformation in the manufacturing process and can only be used for materials with high ductility, resulting in low structural strength and complex processing technology [125,126].”
The fracture toughness of octet-truss lattices (2017, methodology): “A method to design high specific (density scaled) mechanical properties is through the strategic arrangement of trusses in a periodic array, thus creating a cellular material (Gibson and Ashby, 1997; Wadley, 2006; Kooistra et al., 2004; Ashby, 2011).”
