s / Osteoarthritis and Cartilage 25 (2017) S76eS444 S315 When histological items were analyzed individually, it appears that the structure of the cartilage and the proteoglycan content were better correlated with the instantaneous modulus of the femoral condyle (r 1⁄4 0.58, < 0.0001; r1⁄4 0.517, p < 0.0001) thanwith other items. At the tibial plateaus, the strongest associations were found betw...

A theoretical study of structural, electronic, elastic and optical properties of zinc-blende BeS under hydrostatic pressure is presented using ab-initio plane wave pseudopotential density functional theory method within the local density approximation (LDA) and generalized gradient approximation (GGA) .The dependencies of the elastic constants, the bulk modulus, young modulus and energy gaps on...

The influence of the metal content (0-28 at.%) on the structural, mechanical and tribological properties of a-C:Cu films grown by pulsed filtered cathodic arc deposition is investigated. Silicon and AISI 301 stainless steel have been used as substrate materials. The microstructure, composition and bonding structure have been determined by scanning electron microscopy; combined Rutherford backsc...

This paper explores the significance of the inherent strain rate-dependence of many biological materials. Such characteristics are pertinent to computational modelling of these materials for the purposes of surgical robotics and simulation. A pair of 2-dimensional fmite element models of the human brainlvenmcle system are developed and used to analyse the brain structural disease, hydrocephalus...

The goal of this work is to develop and investigate the properties of a new type of multifunctional composite which is based on multi-walled carbon nanotubes (MWCNT). The composite was prepared from a MWCNT “bucky paper” film which was sandwiched between two adhesive layers. Both two point probe and four point probe methods were used to test its mechanical strain sensing properties. The Young’ ...

In this work and in order to consider theoretically the effect of gas hydrates on the mechanical properties of their host sediments, hydrate fraction was introduced as a state variable in the framework of a Critical State model. For the proposed model, the process of de-structuration and softening of natural clay was considered as a proxy for the gas-hydrate-bearing-sediments behaviour. The dev...

Conformal modulus sensors (CMS) incorporate PZT nanoribbons as mechanical actuators and sensors to achieve reversible conformal contact with the human skin for non-invasive, in vivo measurements of skin modulus. An analytic model presented in this paper yields expressions that connect the sensor output voltage to the Young moduli of the epidermis and dermis, the thickness of the epidermis, as w...

We develop a theory of sheaves and cohomology on the category proper modulus pairs. This complements [KMSY21], where non-proper pairs has been developed.

The work present in this paper was developed under the PhD thesis entitled “Application of Data Mining Techniques to the Design of Jet Grouting Columns”. The main goals of this study are the developing of analytical model, by application of Data Mining (DM) techniques, able to estimate the mechanical and physical properties of Jet Grouting (JG) material, namely the evolution of uniaxial compres...

This work shows the Kédougou-Kéniéba inlier (eastern Senegal) pillow lavas behavior from laboratory to field. Some uniaxial tests are carried out on five types of specimens of pillow lavas. These types of specimens are: microscopically healthy rock, fractured rock without filling, fractured rock filled with epidote, chlorite and calcite and rocks with tension crack filled with quartz. The Young...
