Mechanical metamaterials are a class of functional materials with designability and
extraordinary mechanical properties. Due to the manufacturing limitation of traditional …

Auxetic materials and structures have been attracting attention due to their extraordinary
mechanical properties that stand out due to their high capacity to absorb energy. Some …

Micro-selective laser melting fabricated triply periodic minimal surface sheet lattice and
epoxy interpenetrating phase composites (IPCs) are investigated in this paper. To achieve …

Novel auxetic tubes (NAT) were designed, fabricated and examined. Their mechanical
properties were compared with the original auxetic tube (OAT) by the finite element method …

This paper presents a study of 3D novel hybrid auxetic structures made with carbon fiber
reinforced polymer (CFRP) laminate composite based on the stretch-dominated mechanism …

In this work, a novel metamaterial with an enhanced programmable CTE range is proposed
by combing the bi-material bending-dominated chiral unit cell and stretching-dominated …

In this work, a double tubular structure consisting of auxetic tubular structures and aluminum
foam was proposed. The mechanical properties of the aluminum foam-filled auxetic tubular …

Chiral kerf structures are formed by arranging chiral and coiled unit cells which allows for
multi-dimensional and multi-scale shape configurations under mechanical loadings. In this …

The 3D auxetic buckling pattern in the compression process is used to design auxetic
structures. However, obtaining this pattern is time consuming and unintentional. In this …

This study explored the crashworthiness performance of four types of tubular lattice
structures based on triply periodic minimal surfaces (named TPMS-T)—Diamond, Gyroid …
