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

[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
