The effect of using multiple materials within hexagonal and re-entrant (auxetic) cellular
structures was investigated. For each topology, three different material configurations …

The COVID-19 pandemic has resulted in worldwide shortages of nasopharyngeal swabs
required for sample collection. While the shortages are becoming acute due to supply chain …

Auxetic materials with negative Poisson's ratios have important applications across a broad
range of engineering areas, such as biomedical devices, aerospace engineering and …

Auxetic meta-biomaterials offer unconventional strain behaviour owing to their negative
Poisson's ratio (− υ) leading to deformation modes and mechanical properties different to …

Literature on the mechanical performance of additively manufactured (AM) negative
Poisson's ratio (-υ) structures has been primarily focused on beam-based re-entrant …

The present study unravels the deformation mechanisms observed during the static inclined
compression of re-entrant honeycomb (RH) auxetic structure. A pushover Riks analysis is …

This study develops and characterizes the distinctive mechanical features of a stainless-
steel metal stent with a tailored structure. A high-precision femtosecond laser was used to …

Developing cellular materials, especially ordered lattice structures, would allow the
exploitation of structural advantages and enhance the mechanical performances. However …

Auxetic structures provide an interesting approach to solving engineering problems due to
their negative Poisson's ratio, which allows for elongation perpendicular to applied stresses …

This work describes the compression and failure behaviour of multi-honeycomb, re-entrant
honeycomb and silicomb honeycomb structures of various core height (thickness: 10, 20 …
