Implementation of a Modified Anisotropic Creep Model for Clays with Use of the Physics Builder

M. Karlsson [1], J. Yannie [1],
[1] Chalmers University of Technology, Gothenburg, Sweden

In this work a modified anisotropic creep model with structure for soft soils was implemented by using the Physics Builder. The model is validated against boundary value laboratory test such as undrained tri-axial tests and CRS (constant rate of strain) tests. The implemented user ... Mehr lesen

[2]École de Technologie Supérieure, Montréal, QC, Canada

The estimation of the soil saturated hydraulic conductivity (Ks) is crucial in understanding water flow and transport of contaminants. There are many hydrological techniques available in determining this parameter (constant head method, in-situ soil analysis, etc...). While these ... Mehr lesen

Hydrodynamics and Mass Transfer in Taylor Flow

F. L. Durán Martínez [1], A. M. Billet [1], C. Julcour-Lebigue [1], F. Larachi [2],
[1] Toulouse University, Toulouse, France
[2] Laval University, Quebec, Canada

In the present work, numerical simulations of a Monolith Reactor (MR) are carried out in order to develop a pre-design tool for industrial-scale reactors applied to highly exothermal reactions. The reacting circular channels (2-4 mm internal diameter) are coated with a few micron thick ... Mehr lesen

Ion Concentration and Electromechanical Actuation Simulations of Ionic Polymer-Metal Composites

K. J. Kim [1], T. Stalbaum [1], Q. Shen [1],
[1] Department of Mechanical Engineering, University of Nevada, Las Vegas, NV, USA

Ionic polymer-metal composite (IPMC) materials are promising candidates for soft robotics and artificial muscle applications. The primary actuation mechanism in such devices is ion migration in a polymer membrane, localized swelling, and a corresponding overall material deformation, ... Mehr lesen
