An experimental configuration is demonstrated that captures features of the initiation of unstable stress-induced transformation in a shape memory alloy (SMA). The apparatus uses circulating fluids through the grips and a heat sink and thermoelectric devices to control the temperature profile of a specimen within a mechanical testing machine. The configuration can be used to restrict the initia...

Autologous chondrocyte implantation for cartilage repair represents a challenge because strongly limited by chondrocytes' poor expansion capacity in vitro. Mesenchymal stem cells (MSCs) can differentiate into chondrocytes, while mechanical loading has been proposed as alternative strategy to induce chondrogenesis excluding the use of exogenous factors. Moreover, MSC supporting material selectio...

Employing the Ginzburg-Landau phase-field theory, a new coupled dynamic thermo-mechanical 3D model has been proposed for modeling the cubic-to-tetragonal martensitic transformations in shape memory alloy (SMA) nanostructures. The stress-induced phase transformations and thermo-mechanical behavior of nanostructured SMAs have been investigated. The mechanical and thermal hysteresis phenomena, loc...

This paper deals with the thermo-mechanical deformation behavior of shear deformable functionally graded ceramicmetal (FGM) plates. Theoretical formulations are based on higher order shear deformation theory with a considerable amendment in the transverse displacement using finite element method (FEM). The mechanical properties of the plate are assumed to be temperaturedependent and graded in t...

In order to enhance salt rejection level and high pressure mechanical integrity, functionalized nanokaolin decorated multiwall carbon nanotubes (FNKM, 0-5 wt % loading) were incorporated into a cellulose acetate (CA) matrix using high temperature solution mixing methodology. Scanning electron microscopy (SEM), X-ray diffraction technique (XRD), thermo-gravimetric analyzer (TGA) and Fourier tran...

1 INSTRODUCTION In the concept of geological radioactive waste disposal, argillite is being considered as a possible host rock in various countries such as France and Switzerland. This material is chosen thanks to its extremely low permeability that is required to limit the transfer of radioactive elements from the waste package towards the environment. During the construction and exploitation ...

The coupled Thermo-Hydro-Mechanical (THM) behavior of the Callovo-Oxfordian claystone (COx) is great importance for design and safety calculations high-level radioactive waste disposal project in this potential host rock France. heat emitted by causes a pore pressure increase within surrounding essentially due to differential thermal expansion water solid skeleton. low permeability COx its rela...

The last decade has witnessed the emergence of magneto-active polymers (MAPs) as one most advanced multi-functional soft composites. Depending on magnetisation mechanisms and responsive behaviour, MAPs are mainly classified hard magnetic MAPs. Polymeric materials widely treated fully incompressible solids that require special numerical treatment to solve associated boundary value problem. Furth...
