Honeycomb sandwich is really one of the fundamentals to make a composite strong, stiff,
very light, safe and have wonderful performance. Honeycomb materials are majorly used …

This paper developed and fabricated four novel hybrid metamaterial structures by combining
honeycomb, re-entrant, and star-shaped unit-cells by additive manufacturing (AM) …

Prosthetics have come a long way since their inception, and recent advancements in
materials science have enabled the development of prosthetic devices with improved …

The inverse design from property to microstructure is more urgent in practical engineering
than the regular design from microstructure to property. In this paper, a data-driven machine …

The re-entrant auxetic topology was one of the first unit-cells proposed to build cellular
auxetic structures. This unit cell (UC) is still widely used in energy-absorbing systems, but …

In this study, a new vertical strut combined re-entrant auxetic structure was designed and its
mechanical behaviors have been studied. An analytical model was established based on …

To overcome the disadvantages of the re-entrant hexagonal cell (RHC) whose negative
Poisson's ratio characteristic depends on the base angle, and the star-shaped cell (SSC) …

This paper presents a modified re-entrant honeycomb auxetic structure. The structure is
constructed by adding an additional horizontal member between the vertical and re-entrant …

Nowadays, the optimal use of existing energy sources is just as important as the
development of new and alternative energy sources. One of the available and renewable …

Inspired by the idea of springs connected in parallel, a new calculation method for the
nested parallel cell of honeycomb with negative Poisson's ratio (NPR) and Young's modulus …
