Auxetics are a class of structural metamaterials with a negative Poisson's ratio. In
comparison to conventional structures, auxetic structures are proven to exhibit several …

The current communication is a state-of-the-art review of the recently developed
Isogeometric analysis and its various applications such as structural, thermal, fluid–structure …

Due to their exceptional lightweight and mechanical properties, triply periodic minimal
surface (TPMS) based lattice structures have been widely studied. In this paper, the energy …

As a branch of auxetics, the re-entrant hexagonal honeycomb has many superior
mechanical performances. However, most research focused on two-dimensional (2D) re …

Missing rib auxetics with a reinforced central core may have tunable negative Poisson's
ratios (NPRs) and other mechanical parameters. In analogy with the other enhanced …

In analogy with the enhanced hexa-missing rib structure, a novel enhanced anti-tetra-
missing rib structure was proposed in this work. Using a simple energy-based approach …

Sandwich panels find use as energy-absorbing devices and protective structures in various
fields. However, due to their mostly rigid surfaces, they might not meet the protection …

Negative Poisson's ratio (NR) structures have compression-contraction properties. Many
studies have focused on the NR effect of artificially designed microstructures, but very few …

Honeycombs derived from the combination of multiple kinds of structures have better energy
absorption compared with a single structure. A novel bidirectional re-entrant honeycomb …

This review presents developments in structural shape optimization post 2000 from
perspective of numerical analysis techniques. Traditional shape optimization with FEM has …
