An experimental and numerical study of the high cycle multiaxial fatigue strength of titanium lattice structures produced by Selective Laser Melting (SLM)

•Fatigue strength of various cellular structures is assessed using Crossland criterion.•Octet and thin-walled gyroid show the better overall multiaxial HCF resistance.•Three methods to numerically assess the surface roughness effect are compared. A numerical approach is proposed to assess the high c...
