MICROMECHANICAL MODELLING OF PHASE TRANSFORMATION BEHAVIOUR OF A TRANSITIONAL SOIL

引用

Acta Mechanica Solida Sinica 2014年第3期27卷 259-275页

作者： chuang yu Zhenyu Yin Dongmei Zhang College of Architecture and Civil Engineering Wenzhou University LUNAM University Ecole Centrale de Nantes UMR CNRS GeM Nantes France Department of Geotechnical Engineering College of Civil Engineering Tongji University

Experiments show that silts and silty soils exhibit contraction followed by dilation during shearing and the slope of failure line decreases at large strains, termed as phase transformation behaviour. This paper is to develop a new micromechanical stress-strain model that accounts for the phase transformation behaviour by explicitly employing the phase transformation line and its related friction angles. The overall strain includes plastic sliding and plastic compression among grains. The internal-friction angle at the phase transformation state and the void state variable are employed to describe the phase transformation behaviour. The model is examined by simulating undrained and drained triaxial compression tests performed on Pitea silts. The local stress-strain behaviour for contact planes is also investigated.

Synthesis of the Silver Nanofluid by ASNSS Process

引用

过程工程学报 2004年第Z1期4卷 449-454页

作者： Ta-yu chuang Depeartment of Materials Engineering Tatung University Taipei 104 China Deaprtment of Chemical Engineering Yunlin University of Technology Yunlin County China

Arc Spray Nanoparticle Synthesis System (ASNSS) has been used to prepare the silver nanofluids in this study. The metal electrodes under the electrical discharge will melt and evaporate rapidly and condense to form the nanoparticles in the dielectric fluid at lower temperature and produce the suspended nanoparticle fluid. Thus, the mechanism of the ASNSS process is superheating the electrodes by plasma to form metallic nuclei and supercooling these nuclei by dielectric liquid to produce nanofluid. This study considers the different controlling parameters such as discharge current,discharge voltage, pulse-duration time, electrode diameter, and the temperature of dielectric liquid. The optimally operated parameters can be obtained to produce the finer particle size in nanofluid. The results indicate the silver electrodes in alcohol fluid will produce the spherical nanosilver particles. The mean particle size of silver in different dielectric liquid temperatures of-40, -20, 0, and 10℃ is about13.4, 15.8, 17.5, and 21.6 nm, respectively. This indicates that the well suspended fluid can be obtained by controlling the lower dielectric fluid temperature.
