Arcam AB has pioneered additive manufacturing using the electron beam melting (EBM) technology which provides a cost efficient and novel way of producing titanium components for the orthopedic and aerospace industries. In the heart of the EBM technology is the electron beam – whose ... En savoir plus
It is now a well known that the next generation devices in many fields of the semiconductor industry will be based on 3D architectures. In this framework, low thermal budget annealing technological solutions are required. For many applications, either in the field of sensors, ... En savoir plus
Microelectrodes demonstrate that modeling is crucial for understanding the behavior of complex electrochemical systems. The use of the finite element methods in electrochemistry may be of much more general interest for its ability to handle complex geometries. In this context a ... En savoir plus
Railgun is an electrically-powered gun that accelerates a conductive projectile along magnetic metal rails. Various factors increase the projectile velocity. Each method has its own advantages and disadvantages. While increasing the projectile velocity, one has to keep in mind the ... En savoir plus
COMSOL Multiphysics is offering an important alternative to home codes for modeling and simulation of complex problems with including coupled effects on heat and mass transfer. The present work focuses on low Prandtl number fluid melts subject to symmetry breaking and transition to ... En savoir plus
Laser Welded Blank solutions enable to reduce vehicles weight and to optimize their crash performances by means of simultaneous tuning of different grades and thicknesses. The present work aims to characterize numerically and experimentally materials mixing during laser welding. For ... En savoir plus
Shielded transportation casks are commonly used for transportation and storage of radioactive waste materials. Design approval of such casks by regulatory authority is subject to its compliance with a thermal test (among other tests) Due to exposure of cask to fire , there is a ... En savoir plus
Time-dependent multiphysical simulation of pulsed and continuous laser welding of dissimilar metals, based on Moving Mesh (ALE) approach, is proposed. Strong coupling between heat transfer, laminar compressible flow and ALE is used. The model was validated for a case of single ... En savoir plus
