The tensile strength of masonry is relatively low compared to its compressive strength and is affected by the direction of the joints and their filling. In masonry with modern thin layer mortar (joint thickness 3 to 5 mm) sometimes the head joints are left open. A total of 13 model-walls was built and for each model four general purpose mortar combinations and three thin layer mortar combinations ...

Electrical contacts consists of parts where the surfaces are in contact and where the actual physical contact occur just in a few contact asperity points scattered over the whole apparent contact area. Through these contact spots between the two mating bodies the mechanical load and the electric current is transmitted. Often a soft coating is used to enlarge the real contact area. Modeling the ...

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 ...

With detailed hydrodynamic modelling of a system the critical parameters and operation limits can be determined. In the field of fluid dynamic and reactor engineering one of the most important aspects is the practical knowledge of future engineers and technicians. In our research several different reactor constructions and impeller configurations were modelled to achieve a better ...

This paper deals with the design of a viable thermal management solution using La5Ca9Cu24O41 layers for heat channeling. The simulations are carried out with the finite element method using COMSOL Multiphysics Heat Transfer Module. COMSOL 4.2 was used to model and optimize silicon devices. Malfunctioning elements on silicon devices are sometimes converted into hotspots resulting in the ...

Many optoelectronic devices utilize a heterojunction of a pair semiconducting materials including high-efficiency MEMS devices, solar cells, LEDs, and VCSELs. One fabrication technique which achieves such a device is direct wafer fusion. To optimize the process, COMSOL Multiphysics 4.0 was used to test various geometric configurations of the fixture. 2D and 3D models were created in order ...
