Elasto-Plastic FEM Models Explain the Emplacement of Shallow Magma Intrusions in Volcanic Complexes

A. Bistacchi[1]
[1]Università degli Studi di Milano Bicocca, Milano, Italy

We present numerical models and field data that aid understanding of volcano-tectonic processes related to the propagation of inclined sheets and dykes under a stress field resulting from the inflation of a shallow magma chamber. Structural field data from the classical Cuillins cone ... Read More

Structural Mechanics for Real Geometry of Basalt Woven Composites

J. Salacova[1]
[1]Technical university of Liberec, Department of Material Engineering, Liberec, Czech Republic

Woven composites with basalt reinforcement plain 1x1 are examined to define structural mechanics. Woven composites were created by the prepreg technology, 8 layers of plain-weave basalt fabrics were saturated by the precursor, polysiloxane matrix Lukosil®, and joint pressed during ... Read More

Detector and Calibration-source Models for the SAFARI Detector Test Facility

[1]SRON Netherlands Institute for Space Research, Groningen, The Netherlands
[2]National University of Ireland, Maynooth, Ireland

SAFARI is a far-infrared imaging spectrometer for the Japanese satellite observatory SPICA. SAFARI covers the wavelength range 34—210 μm (1.4—8.8 THz) using Transition-Edge-Sensor (TES) bolometers. We have built a test facility to qualify and characterize the SAFARI focal plane units ... Read More

Influence of Thermal Conductivity and Plasma Pressure on Temperature Distribution and Acoustical Eigenfrequencies of High-Intensity Discharge Lamps

J. Schwieger[1], B. Baumann[1], M. Wolff[1], F. Manders[2], J. Suijker[2]
[1]Heinrich-Blasius-Institute of Physical Technologies, Hamburg University of Applied Sciences, Hamburg, Germany
[2]Philips Lighting, Turnhout, Belgium

High-intensity discharge (HID) lamps are energy-efficient light sources with excellent color qualities. A three-dimensional model of a low-wattage lamp, which includes plasma, electrodes, and burner walls, was developed in COMSOL Multiphysics®. Most parameters appearing in the coupled ... Read More

Prediction of Temperature and Thermal Stress in Plasma Sprayed Coatings new

M. Raja[1] , G. Hiremath[1], K. Ramachandran[1], P.V.A. Padmanabhan[2], T.K. Thiyagarajan[2]
[1]Karunya University, Coimbatore, Tamil Nadu, India
[2]Bhabha Atomic Research Centre, Mumbai, Maharashtra, India

Plasma spraying is one of the prominent technologies for wear, corrosion and high temperature resistant coatings. The coating quality is very important to increase the performance of the components as well as to protect the outer surface of the component from external environment. The ... Read More

Multiphysics Study into Compression Rings, Coated Against Uncoated new

[2]Racing to Research Team, School of Computing, Engineering & Physical Sciences, University of Central Lancashire, Preston, UK
[3]School of Computing, Engineering & Physical Sciences, University of Central Lancashire, Preston, UK

Internal combustion engine components have been a main research interest over many decades. The structural mechanics and dynamics of the piston rings has been a large focus of work in order to gain a greater understanding of the how the piston ring dynamics affect the piston ring. ... Read More

Purcell Effect via Numerical Simulation new

I. Zabkov [1], V. Klimov[1], A. Pavlov[1], D. Guzatov[2]
[1]All-Russia Research Institute of Automatics (VNIIA), Moscow, Russia
[2]Yanka Kupala State University of Grodno, Grodno, Belarus

As it is known nano-sized emitters (such as atoms, quantum dots and point defects in diamonds) interaction with nano-environment leads to drastic changes of their decay rate and therefore lifetime (Purcell effect). To calculate the influence in general one needs to solve equations of ... Read More

Computational Simulation of Gold Core/Shell Nanostructures for Near-Field Transducers in Heat-Assisted Magnetic Recording new

J. Bennington[1]
[1]Queen's University Belfast, Belfast, Northern Ireland, UK

A recurring problem, in heat assisted magnetic recording is the build-up of thermal energy in the near-field transducer leading to NFT deformation and the cessation of operation. A mechanism to dissipate this excess heat in the NFT without greatly effecting its’ plasmonic response is ... Read More

Simulation of a Piezoelectric Loudspeaker for Hearing Aids and Experimental Validation new

G. C. Martins[1], P. R. Nunes[1], J. A. Cordioli[1]
[1]Federal University of Santa Catarina, Florianópolis, SC, Brazil

The use of piezoelectric materials in hearing aid loudspeakers, also called receivers, presents technical and economic advantages such as reducing the number of parts of the system and its manufacturing cost.
