Physical and mechanical studies of Alcantara® have shown very pronounced anisotropic nonlinear features. Using constitutive equations borrowed from the modelling of biological tissues like tendons and/or arteries under the form of hyperelastic free-energy functions, a good representation of such mechanical features can be obtained. In particular, a combination between the optimization module ...

The Large Hadron Collider at CERN has begun operations at 7 TeV center of mass energy. CERN plans to run at this energy until the end of 2012 with the goal of providing an integrated luminosity of a few fb?¹ to the CMS and ATLAS experiments. The LHC will then shut down for 1.5 to 2 years to make the revisions necessary to run at ~14 TeV. Operation resumes in 2014. In 2017/18, there will be ...

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. Coupling the finite elements analysis done by COMSOL with a recursive CBED and LACBED dynamical simulation, we are ...

In this study, magneto-rheological elastomer (MRE) composite beams made of Barium hexaferrite (BaM) and Iron (Fe) powders combined with a highly-compliant matrix material were simulated using COMSOL\'s Solid Mechanics and AC/DC modules. The goal of the work was to develop models capable of predicting the actuation behavior of hard- and soft-magnetic MREs. This work simulates the bending of the ...

In semiconductor gas sensors, the base of the gas detection is the interaction of the gaseous species at the surface of the semiconducting sensitive material. Since the chemical reactions at the surface of the sensor material are functions of temperature. We simulate our µHeater design on a Buckled Cantilever Plate (BCP). Such structure allows the sensor to be suspended for thermal insulation. ...

In solid mechanics, there is considerable interest in achieving “invisibility”. The applications in mechanics include protection of structures and parts of structures from potentially harmful transient waves and steady state vibrations. A suggested large scale application is that protection against seismic waves from earthquakes could be achieved by using cloaking to re-route the waves around ...
Viscoelastic Mechanical Analysis for High Temperature Process of a Soda-Lime Glass Using COMSOL Multiphysics
Material and Production Engineering Department, University of Naples “Federico II”, Naples, Italy
Glasses are widely used in the modern industry. For high temperature the glass behaves very much like a Newtonian liquid with temperature-dependent viscosity. The goal of this study is to set a numerical procedure in order to study the glass forming process of soda-lime glasses used in the automotive field by means numerical simulations.

Aus technischen, ökologischen und ökonomischen Gründen nimmt die Dauerhaftigkeit von Stahlbetonbauwerken in der heutigen Zeit einen immer größeren Stellenwert ein. Schadensursachen an solchen Bauwerken werden oft durch chemisch-physikalische Prozesse, wie z.B. den kapillaren Transport betonaggressiver Wässer in die Betonrandzone, hervorgerufen. Um nun die Dauerhaftigkeit bzw. die ...

Finite element models using COMSOL Multiphysics and MATLAB were developed to solve the problem of stress distribution interior homogeneous, isotropic, incompressible elastic solid material under known vertical external compression with a rectangular contact surface. Moreover, comparison between these results and analytical solutions was used to further validate that stress drops off with ...

The two wooden cabinets of Jan van Mekeren that are located in Amerongen Castle show comparable wood damage; in particular large cracks in the cabinet doors are clearly noticeable. It is assumed that these cracks were caused by bad indoor climate conditions in the castle. Combined computational modelling of the indoor climate conditions in the castle and the hygroscopic and mechanical ...
