Finite Element Model of a Ferroelectric
Ferroelectric technology continues to attract significant interest due to its wide range of applications (capacitors, nonvolatile memories, accelerometers ...). In this work we present a finite element model of a ferroelectric. Piezoelectric and ferroelectric matrix are included. The ... En savoir plus
Modeling of Vickers indentation of TiAl alloys
Instrumented indentation is increasingly used as an alternative non-destructive test method to measure mechanical properties of small volumes of materials. In this work, the instrumented indentation test is applied as a non-destructive method to assess the mechanical properties of TiAl ... En savoir plus
Fruit Optical Properties Assessment by Means of Spatially Resolved Spectroscopy
Since the invention of laser sources, understanding the interaction between the laser and biological tissues is a subject of great importance because of their medical applications in particular for diagnostic purposes. They recently found a growing interest in the sector of the ... En savoir plus
From customer requirement to product requirement with COMSOL
Anders B Nilsson graduated M. Sc. in engineering physics from Lund University in Sweden. He has been working in the R&D department at BD Medical as principal engineer and project leader since 2005. He uses COMSOL for a wide range of functions, such as early concept development and ... En savoir plus
An MHD Modeling of High-Temperature SiC Solution Growth
Despite its real advantages compare to seeded sublimation growth, SiC solution growth has never given convincing results. The difficulty of stabilizing the growth front, and thus avoiding any polycrystal formation results from a poor description and understanding of the coupled phenomena ... En savoir plus
Using Computational Fluid Dynamics Model to Predict Changes in Velocity properties in Stented Carotid Artery
Atherosclerosis is a disease that narrows, thickens, hardens and restructures a blood vessel due to substantial plaque deposit. In the Carotid Artery, the decision to treat using endarterectomy and stenting is determined by the velocity as measured by Doppler flow in the common Carotid ... En savoir plus

The presented paper is a qualitative study of power device results from electro-thermo-mechanical simulation. This study particularly interested in the ... En savoir plus
A Model of Gas Bubble Growth by COMSOL Multiphysics
We use COMSOL Multiphysics to model a gas bubble expansion in a viscous liquid initially at rest, a very common system for lightweight foamed materials from metal production and polymer processing. Modelling and simulation of foam processing during the production step involves many ... En savoir plus
