TL;DR: In this paper, a review of 2D and 3D chiral mechanical metamaterials is presented, and their mechanical behaviors and deformation mechanisms can be investigated through equilibrium principle, strain energy analysis, micropolar elasticity and homogenization theories.

TL;DR: A probabilistic framework is proposed for fatigue life assessment of notched components under size effects, in which the Smith–Watson–Topper damage parameter is utilized to characterize the multiaxial stress state at the notch tip.

TL;DR: In this paper, two types of innovative chiral stents with auxetic properties are proposed: (a) anti-tetrachiral stent with circular and elliptical nodes; (b) hierarchical anti-to-torch-clustering stent.

TL;DR: In this article, a combined critical plane approach with the theory of critical distance for fatigue analysis of notched components under multiaxial loadings is discussed. And the influence of employing the point method and the line method on predicting performance as well as the rationality of regarding the critical distance as a material constant or as a function related to fatigue life are investigated.

TL;DR: In this paper, three-dimensional lattice structures composed of octet-truss and truncated-octahedron unit cells with regular and tapered beams are proposed, and their mechanical properties are investigated through experiments and simulation comparisons.
