Nonlinear Constitutive and Mechanical Properties of an Auxetic Honeycomb Structure
Mathematics, 2023 Auxetic honeycomb has unique mechanical properties such as good energy absorption capacity, tensile strength and fracture toughness, etc. Therefore, honeycomb with a negative Poisson’s ratio is used widely in medical, biological, aerospace and other ...

Design of a Multistable Finger Prosthesis with Programmable Metamaterials
Advanced Engineering Materials, EarlyView.This research article shows the development of a multistable programmble metamaterial for the use as a finger prosthesis. The material was designed on different hierarchical levels where the influence of geometrical parameters and combination of mechanical elements was explored.

Auxetic Black Phosphorus: A 2D Material with Negative Poisson’s Ratio
, 2016 The Poisson’s ratio of a material characterizes its response to uniaxial strain. Materials normally possess a positive Poisson’s ratio - they contract laterally when stretched, and expand laterally when compressed.

Unique Omnidirectional Negative Poisson’s Ratio in δ-Phase Carbon Monochalcogenides
, 2020 Auxetic materials (negative Poisson’s ratio) are of exceptional importance for nanomechanical applications. Using first-principles calculations, we propose two-dimensional δ-phase carbon monochalcogenides (δ-CS, δ-CSe, and δ-CTe) with very strong ...

Advanced Engineering Materials, EarlyView.This study examines Invar composites reinforced with titanium carbide (TiC) and titanium nitride (TiN) using laser powder bed fusion (LPBF). It presents the influence of reinforcements on microstructure, tensile properties, and thermal expansion. Results show that TiC effectively strengthens Invar while maintaining low thermal expansion, whereas TiN ...

Advanced Functional Materials, EarlyView.Ferroelectric nanoclusters create local internal fields in a normally non‐switchable polar film because of polarization mismatch at their interfaces. That field opposes polarization in the regions with larger polarization and reinforces polarization in the regions with smaller polarization.

Rippled blue phosphorene with tunable energy band structures and negative Poisson’s ratio
AIP Advances, 2023 Recent successes in the discovery of novel two-dimensional (2-D) phosphorene allotropes have motivated more in-depth investigations into tuning their properties through precise geometric control.
