FRACTURE BEHAVIOR OF CELLULAR STRUCTURES OBTAINED BY SELECTIVE LASER MELTING
DOI: 10.17804/2410-9908.2020.4.035-047 An example of samples with a cellular architecture, obtained by selective laser melting,
is used to study the influence of the building direction of cellular objects on the characteristics of fracture under cyclic loading. The origin of their fracture has been revealed. The mechanism providing increased fatigue fracture resistance of objects which, along with the cellular structure, have anisotropy of properties due to the technological features of their production has been determined.
