[1] Computer, Electrical and Mathematical Sciences and Engineering (CEMSE), King Abdullah University of Science and Technology (KAUST), Saudi Arabia
[2] The University of British Columbia, School of Engineering, Okanagan Campus, Saudi Arabia

For our simulation we used the Piezoelectric Devices interface. The structure was set with (clamped) fix constraint boundaries to both ends. The bottom electrode was set to be the ground for the electrostatic physics and the top electrode was set to be a Terminal with potential of 10V. A ... Read More

Toroidal Spring Coil: Displacements & Stress Analysis to Detect the Sealing Parameters

V. Riccardi [1],
[1] Cesare Bonetti, Garbagnate Milanese, Italy

The aim of the simulation is to study the behavior of a particular arrangement of a sealing system made of a Toroidal Spring Coil encapsulated in an thin casing, which is provided with a circumpherential cut to permit the pressure fill it inside. The mechanical simulation implemented ... Read More

Simulation of the Earth's Electromagnetic Clearance System (DEMETER)

J. P. Pothin [1], N. Gosselin [1],
[1] Nexter Systems, France

DEMETER is a magnetic field replicator. This system is designed to deceive anti tank mines. Numerical simulation (using COMSOL Multiphysics® software) allows to indicate DEMETER's performance in various environment and various configurations. The study of the magnetic field provide also ...
