A Multi-Material Projection Stereolithography System for Manufacturing Programmable Negative Poissons Ratio Structures
… negative Poissons ratio honeycomb reentrant structures are realized. Researchers have been studying auxetic structures over decades, the mechanical property control of auxetic structure mainly relies on geometry design in previous studies. Now with the help of EMSL system, other design …

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 …

Ex Vivo Deformations of the Uterosacral Ligaments
… ligaments (USLs) are important anatomical structures that support the uterus and apical vagina within the pelvis. As these structures are over-stretched, become weak, and exhibit laxity, pelvic floor disorders such as pelvic organ prolapse occur. Although several surgical procedures to …

Experimental Testing and Numerical Investigation of Materials with Embedded Systems during Indentation and Complex Loading Conditions
… systems in a half space. The influence of auxeticity on the indentation stiffness ratio and the de-formation of the embedded system under different conditions (indenter size, thickness and embedment depth of the embedded layer) was established and key mechanisms of the Poisson’s ratio …

Design and optimization of lattice structures and mechanical metamaterials for additive manufacturing
… and additive manufacturing (AM) of lattice structures and mechanical metamaterials. These materials, characterized by their cellular nature, possess unique properties primarily determined by the design of their individual cells rather than the properties of the bulk material from which they …

Experimental and Numerical Study of Ductile Metal Auxetic Tubular Structures
… the risk posed by seismic and blast loads to structures are of high interest to researchers. Auxetic structures are a new class of metamaterials that exhibit counterintuitive negative Poisson's ratio (NPR) behavior based on their geometric configuration. Cellular auxetics are light-weight and …
