Multiaxial mechanical characterization of additively manufactured open-cell Kelvin foams

Erdong Wang et al.

Summary: Open-cell Kelvin lattice structures (Kelvin foams) are fabricated through the SLM process and the multiaxial mechanical behaviors of these foams are studied. It is found that the yield surface of the Kelvin foams gradually shrinks with increasing dimensional tolerance induced by the SLM process, especially under hydrostatic compression. The influence of foam filler on the yield surface is weakened when experiencing hydrostatic compression.

Auxetic boosting of confinement in mortar by 3D reentrant truss lattices for next generation steel reinforced concrete members

Georgios Tzortzinis et al.

Summary: This study presents a new method for confining concrete/mortar materials using steel auxetic truss lattice reinforcement, which shows enhanced confinement, significant strength increase, and high residual strength compared to plain mortar specimens.

The in-plane elastic-plastic response of an incompressible, filled hexagonal honeycomb

H. Tankasala et al.

Summary: Exact solutions are derived for the small-strain, in-plane, elasto-plastic response of a hexagonal honeycomb using slender beam theory. The study explores the macroscopic shear compliance and low shear strength of the incompressible hexagonal honeycomb, as well as the elevated tensile modulus and strength due to bar stretching. Explicit analytical formulae are obtained for the macroscopic tensile modulus and strength of the incompressible honeycomb.
