In order to investigate the implantation of microprobes into brain tissue, we developed a finite-element and a physical model to replace real biological tissue for mechanical testing. Penetrating forces of a tungsten indenter into a layered structure was investigated with different indentation speeds. Numerical and physical model are in good correspondence to each other and reproduce measured ...

During the welding of tantalum with a ND: YAG pulsed laser, a deep and narrow cavity, called the keyhole, is formed. At the end of the process, surface tension forces provoke the collapse of the keyhole. For important interface deformations, gas bubbles can be trapped into the melting pool. If the solidification time is insufficient, these bubbles give birth to residual porosities. The aim of the ...

In this work we want to explore some techniques, microfluidic and electrospray-ionization based, suitable for dynamic microarrays\' fabrication. The fabrication techniques are based on manipulation and self-assembly of selective coated micro and nanobeads. The simulation will include electro-osmotic flow, species transport, and electrostatics.

Simulation tools for building physics problems play an important role in design and understanding the behavior of energy efficient buildings. There are different tools available for simulation of these problems, but each simulation tool has its own advantages and limitations. In this paper, a heat transfer problem in an exterior building wall with high performance materials has been simulated in ...

This paper will present a numerical model based on COMSOL Multiphysics suited to simulate the dynamic response of a catenary mooring (or a submarine cable). In general, mooring lines are subject to a direct wave load (e.g. drag, inertia) in addition to the movement of the vessel to which they are linked. Tests were carried out at the wave flume of the Maritime Laboratory of IMAGE Department, ...

Since the invention of laser sources, understanding the interaction between the laser and biological tissues is a subject of great importance because of their medical applications in particular for diagnostic purposes. They recently found a growing interest in the sector of the arboriculture to check the fruits quality in a non-destructive way. In this work, we study the interaction between the ...

We report a numerical study on the blood – magnetic carrier aggregate flow in an external magnetic field, for applications such as magnetic drug targeting. The arterial system morphology is complex and patient-related therefore more realistic numerical simulations request medical image-based reconstruction to generate computational domains. Simpleware package is used to generate the ...

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 ...

We deal with Liquid Crystal Elastomers (LCEs) having hybrid alignment (HNEs), that is, fabricated with a given non-homogeneous nematic orientation. For such a materials, permanent distortions induced by deswelling can be compensated by those resulting from cooling below the transition temperature, thus yielding the possibility of producing temperature-driven actuators. Here, we simulate the ...

Modeling electromechanical actuation of ionic polymer-metal composite (IPMC) material is considered in this work. Ionic current in the polymer is described with the Poisson-Nernst-Planck system of equations. Calculated ionic concentration is related to the deformation of the material. To include the effect of the electrodes, the ionic current and the electric current in the electrode domains is ...
