Hierarchical Fibers with a Negative Poisson’s Ratio for Tougher Composites [PDF]

open access: yes, 2013
In this paper, a new kind of hierarchical tube with a negative Poisson’s ratio (NPR) is proposed. The first level tube is constructed by rolling up an auxetic hexagonal honeycomb.

Permeability and dynamic elastic moduli of controlled porosity ultra-precision aerostatic structures [PDF]

open access: yes, 2014
Porous ceramic aerostatic bearings enable precise and smooth motion and improved stiffness compared with widely used orifice restrictor bearings. However, the processing techniques so far used are too complex or rely in lowering the sintering temperature

Mathematical models for nonlocal elastic composite materials

open access: yesAdvances in Nonlinear Analysis, 2017
In this paper we derive and solve nonlocal elasticity a model describing the elastic behavior of composite materials, involving the fractional Laplacian operator.

Elastic potentials as yield surfaces for isotropic materials.

open access: yesPLoS ONE, 2022
This paper proposes that elastic potentials, which may be rigorously formulated using the negative Gibbs free energy or the complementary strain energy density, may be used as the yield surface of elasto-plastic constitutive models.

Polyurethane-modified room-temperature curing epoxy super adhesive for artifact restoration and light emitting diode encapsulation

open access: yesMaterials & Design
Epoxy adhesives are widely used for their strong adhesion but face challenges due to high curing temperatures and brittleness, limiting their application in precision manufacturing and fine industries.

Hydraulic Abrasion-Resistant Elastic Epoxy Resin Materials

open access: yesAdvances in Materials Science and Engineering, 2019
The abrasion of hydraulic concrete structures caused by the washing action of flowing water is a common problem and cannot be solved by simply increasing the strength of the concrete.

Ellipticity loss analysis for tangent moduli deduced from a large strain elastic–plastic self-consistent model [PDF]

open access: yes, 2009
In order to investigate the impact of microstructures and deformation mechanisms on the ductility of materials, the criterion first proposed by Rice is applied to elastic–plastic tangent moduli derived from a large strain micromechanical model combined ...

Entropy change-induced elastic softening of lithiated materials

open access: yesTheoretical and Applied Mechanics Letters, 2015
To understand the “elastic softening” of Li–Si alloys for the development of Li-ion batteries, the effect of stress-induced change of entropy on the mechanical properties of lithiated materials is examined within the theories of thermodynamics and linear
