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 an overview of mine-clearing tools disturbances on the field generated by DEMETER.

Intervertebral discs (IVD) are fibro-cartilages situated between vertebrae providing their joint flexibility. They play a major role in the transmission and absorption of load through the spine. The disc can undergo progressive structural and quantitative changes in its composition and morphology related to mechanical load applied to the spine which can lead to disc degeneration; this disease is ...

Introduction: Ongoing work to improve water and carbon dioxide separation systems to be used on crewed space vehicles combines sub-scale systems testing and multi-physics simulations. Thus, as part of NASA’s Advanced Exploration Systems (AES) program and the Life Support Systems Project (LSSP), fully predictive COMSOL Multiphysics® software models of the Four Bed Molecular Sieve (4BMS) of the ...

With the development of micro and nanotechnologies, integrated structures based on piezoelectric thin films are widely investigated and their characterization become a crucial issue for the development of new applications. A laser interferometry is here used to assess the mechanical response in quasistatic regime of a piezoelectric sample. To complete this experimental approach, a numerical ...

Organic-rich shale resources remain an important source of hydrocarbons considering their substantial contribution to crude oil and natural gas production around the world. Moreover, as part of mitigating the greenhouse gas effects due to the emissions of carbon dioxide (CO2) gas, organic-rich shales are considered a possible alternate geologic storage. This is due to the adsorptive properties ...

Micro-machined ultrasound transducers have a wide range of applications. As a sensor or actuator they can be used for measuring fluid speed and direction, to mix and excite particles (sonication), for taking images (ultrasonography), for non-destructive testing and many other purposes in wide variety of fields. For this particular study, a simplified model of micro-machined piezoelectric ...

This paper describes the use of structural mechanics capabilities within COMSOL to explore new cooling catheter designs. Cooling catheters may be used to save ischemic tissue resulting from strokes or heart attacks. Typical guide catheters use metallic braiding to ensure torsional strength. Braiding, however, displaces space for flows and limits design options. To explore alternatives to ...

In volcanic areas, the presence of heterogeneous materials and high temperatures affect the rheological behaviour of the Earth's crust that calls for considering the anelastic properties of the medium surrounding the magmatic sources. A thermo-mechanical numerical model is performed for evaluating the temperature dependency of the elasto-plastic solution. Both temperature distributions and ...

This paper presents a novel methodology towards the design, analysis, and the fabrication process involved in developing a cost effective method to create a piezoelectric actuator by means of the flexoelectric effect. The basic physical equations of the flexoelectric effect and the qualitative analysis of the flexoelectric actuator are done using COMSOL Multiphysics. This effect is used to align ...
