TL;DR: In this paper, the effect of multiaxial loading scenario on surface topography in notched samples made of high-strength steels processed by both conventional and additive manufacturing techniques was studied.

TL;DR: In this paper, the multiaxial fatigue behavior of steel samples produced by selective laser melting was studied and the cyclic plasticity at the notch-controlled process zone was accounted for by combining the equivalent strain energy density concept and the theory of critical distances within a linear-elastic framework.

TL;DR: In this article, the relationship between fracture surface morphology, fatigue loading conditions and notch radius was analyzed using fractal analysis for quantification of the geometry of the fracture surface, which may serve as a basis for extracting fatigue loading information from fracture surfaces of destroyed materials and structures.

TL;DR: In this paper, the influence of material isotropy on fatigue fractures using metrological methods is presented, and the post-failure analysis of the fatigued fracture in the context of surface topography parameters is dealt with.

TL;DR: This work compared both the crack propagation and rupture roughness profiles based on areal parameters for total fracture area to show a great impact of the loading scenario on both the local profiles and total fracture areas.
