Modeling of Thermal Load and Electric Fields in Microfocus X-Ray Tubes

Dr. Vladimir Burlaka1, Thorsten Fröba1
1X-RAY WorX GmbH, Siemensstraße 26, 30827 Garbsen, Germany

The thermal load on the system components is one of the technical problems in the development of microfocus X-ray tubes. To improve their stability in long-term use, it is important to understand the physical phenomena and their influence on the system stability and filament lifetime. To ... Read More

Analysis of Contact Stiffness in Hammer to Anvil Collision for Pyroshock Purposes

Alessandro Daga1, Luca Viale1, Luigi Lentini1
1Politecnico di Torino

When dealing with space and aerospace equipment, their ability to withstand the strong excitations produced during the launch must be tested by the manufacturers according to international standards requirements. In fact, structural subsystems of the rockets are commonly released by ... Read More

Finite Element Analysis of Friction Stir Welding of Al Alloy and Inconel 718

Ahmed Abotaleb1, Yves Remond1, Said Ahzi1
1University of Strasbourg, ICUBE laboratory – CNRS, 2 Rue Boussingault, 67000 Strasbourg

Friction Stir Welding (FSW) is a solid-state joining technique that has become increasingly popular and efficient for welding both similar and dissimilar metallic materials. Despite its success in joining dissimilar materials, further development is necessary to meet industry ... Read More

Modeling of Thermal Expansion of a Material During its Cooling Using COMSOL Multiphysics®

A. CLARISSOU1, V. BRUYERE2, P. NAMY2, I. CRASSOUS1
1FRAMATOME, 60 Avenue Paul Girod, 73400 Ugine France
2SIMTEC, 5 rue Felix Poulat, GRENOBLE, FRANCE

In metallurgy, the use of numerical models is popular because of the many coupled physical phenomena that occur during the various processes. For instance, the resulting shape and metallurgical state of a material are very sensitive to changes in temperature. The drop in temperature of ... Read More

1Department of Optics and Photonics, Wroclaw University of Science and Technology, Wroclaw, Poland

For the purpose of investigation the inertial behaviour of the crystalline lens, the COMSOL Multiphysics® software was used to create a 2D multi-physics model of the porcine eye globe, by using the Fluid-Structure Interaction (FSI). The geometry of the porcine eye model was adapted from ... Read More

Heat Transfers and Solid Mechanics in Microarchitectured Materials Using Periodic Homogenization

F. Viry1, J.-D. Wheeler1, P. Namy1
1SIMTEC, Grenoble (France)

Microarchitectured materials are generally made of different compounds bound at the microscopic level using a periodic pattern. This results in a macroscopic material with new properties arising from each of the individual compound properties and the way the microarchitecture binds them. ... Read More

3D Numerical Simulation of Resistance Sintering for Electrical Contact Applications for Breakers
