Bistable Auxetic System -- Programming synclastic curvature into 2D Patterning
… inspiration from the transformation process of auxetic materials and embeds this within a bi-stable mechanism. Starting from fundamental geometric research of linear hinges and out-of-plane rotation, geometrical constraints are identified thoroughly for the length-preserving transformation …

Additive manufacturing of stiffness optimised auxetic bone scaffold using cobalt-chromium-molybdenum superalloy
Auxetic materials offer unconventional strain behaviour owing to their negative Poisson’s ratio (−𝜐) leading to deformation modes and mechanical characteristics different to traditional porous architecture. This can lead to favourable outcomes for load-bearing tissue engineering constructs, such as …

Design, production and evaluation of an auxetic straining device for application in lung tissue engineering scaffolds
… on the negative Poisson’s ratio exhibited by auxetic materials, it was possible to translate uniaxial loading into biaxial expansion. Poly-L-lactide and polypropylene re-entrant honeycomb auxetic meshes were 3D-printed and incorporated into collagen scaffolds. Computational simulations were …

Additively manufactured aluminium auxetic architecture with targeted mechanical and energy absorption characteristics
Auxetic materials offer unconventional properties owing to their negative Poisson’s ratio (−𝜐) leading to deformation modes and mechanical characteristics different to traditional porous architecture. This leads to favourable outcomes for lightweight applications where precise control of the …

Isogeometric topology optimization for auxetic metamaterials and structures
… structures and structures with multiple materials. Meanwhile, the proposed topology optimization method is also applied to implement the rational design of auxetic metamaterials and auxetic composites. In Chapter 1, we provide a brief description for the main intention of the current …

Experimental Testing and Numerical Investigation of Materials with Embedded Systems during Indentation and Complex Loading Conditions
… and used to study the deformation of soft materials with different embedded systems under indentation and more complex conditions. The deformation of a soft material with an embedded stiffer layer under cylindrical flat indenter was investigated through FE modelling. A practical approach in …
