The press and blow (P&B) process is widely used to produce glass containers. While the P&B process has demonstrated to be capable of reducing container weight by as much as 33%, it can also induce the formation of micro-checks that weaken container strength. This paper presents ... En savoir plus
The present work formulates the dynamics of a slender structure as a long beam. This results in a PDE that is fourth-order in space, and second order in time. In COMSOL the coupling method is used to decompose this problem into two second-order equations, one for displacements, and one ... En savoir plus
The application of shape memory alloys (SMA) as actuators in smart structures is a quickly developing field. The particular focus of this paper is on the aspects of modeling and simulation of adaptive structures with integrated SMAs using the finite element method (FEM). A number of ... En savoir plus
Strained technology is being promoted as the best way to extend the performance of semiconductor transistors. An inhomogeneous layer deposited on top of a silicon device can induce a strong modification in the real silicon strain state, and consequently in its electronic performance. ... En savoir plus
Among the several types of capacitors, the double-layer and redox types have gathered increasing attention to address some of the heavy power demands of modern technology. In redox capacitors, charge is stored chemically via oxidation/reduction processes in the active materials like ... En savoir plus
The paper attempts to give a contribution to the dynamic analysis of musical instruments. A multidisciplinary approach oriented to the study of mechanical, structural, vibratory and acoustical phenomena related to stringed instruments is discussed. The case study focused in this paper ...

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 ... En savoir plus
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 ... En savoir plus
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 ... En savoir plus
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 ... En savoir plus
