A numerical analysis on transient three-dimensional temperature distribution in a semi-infinite solid, irradiated by a moving Gaussian laser beam, is carried out numerically by means of the code COMSOL Multiphysics. The investigated workpiece is simply a solid. A laser source is ... Per saperne di più
It is commonly recognized that careful thermal design of electronic equipments represents an unavoidable pre-production step in order to ensure reliability and performance of those components during their functioning. This paper mainly concerns a comparison between experimental and ... Per saperne di più
Two friction stir welding models are presented – a global thermal model using the temperature dependent heat source and a local material flow and heat generation model allowing for detailed investigation of different contact conditions. The two models are coupled into a larger local ... Per saperne di più
Within this paper the so called “birth and death” method is demonstrated in use with COMSOL Multiphysics®. With this method the free and reactionless movement of a solid structure on deformed geometries and the activation of this solid structure at later simulation steps is possible. For ...

The key issues of the Fraunhofer Institute for Solar Energy Systems are research and development of solar technologies for the fast growing market of solar energy. This paper presents examples of the usage of COMSOL Multiphysics: The ingress of water is a serious reason for the ... Per saperne di più
The Cosserat models fall into the group of the extended continuum media. They are capable of treating the size effects (characteristic length) in a natural manner using six material moduli for the isotropic elastic cases instead of two (and) for the classical continuum mechanics. This ... Per saperne di più
Strain induced by local deformation of a flexible micrometer-sized semiconductor tube is quantified by modeling a ball pressing on the tube wall. By changing the pressing condition, we are able to change the strain state of the tube wall incorporating self-assembled quantum dots (QDs) in ... Per saperne di più
This paper presents a hybrid finite element – finite volume algorithm for solving multi-scale fluid-structure interaction during transient operation of a hydraulic rod seal. The elasto-hydrodynamic model consists of several micro-scale and macro-scale analyses types, all incorporated in ... Per saperne di più
The residual stresses developed in a stiffened panel manufactured using Electron Beam Freeform Fabrication (EBF3) process were studied. EBF3 process is a layer additive process that can be used to build near-net shaped parts directly using computer controlled techniques, which can be ... Per saperne di più
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 ... Per saperne di più
