Auxetic cellular structures have garnered huge research interest as a candidate for energy
absorption due to their appealing features, including extremely high indentation resistance …

Auxetic materials (or metamaterials) are those with a negative Poisson ratio (NPR) and
display the unexpected property of lateral expansion when stretched, as well as an equal …

The work describes a cellular structure configuration with a rectangular perforation topology
exhibiting auxetic (negative Poisson's ratio) in‐plane behaviour. The rectangular voids used …

A generic degree-4 vertex (4-vertex) origami possesses one continuous degree-of-freedom
for rigid folding, and this folding process can be stopped when two of its facets bind together …

We seek monolithic topologies for constant output (CoFM) and input (CiFM) force
mechanisms using topology optimization. We capture large displacements, buckling, contact …
