Influence of Vickers Indenter Tip Geometry on the Macro-indentation Properties of TiAl Alloys

G. Maizza, and R. Cagliero
Politecnico di Torino
Dipartimento di Scienza dei Materiali ed Ingegneria Chimica
Torino, Italy

In this work the influence of the geometry of the Vickers indenter tip on relevant indentation properties is investigated during instrumented indentation operated in the macro range (i.e. with forces ranging from 2 to 200 N) and carried out in the case of a homogenized (i.e. heat ...

Simulating HFIR Core Thermal Hydraulics Using 3D-2D Model Coupling

A. Travis[1], K. Ekici[1], J. Freels[2]
[1]The University of Tennessee, Knoxville, TN, USA
[2]Oak Ridge National Laboratory, Oak Ridge, TN, USA

A model utilizing interdimensional variable coupling is presented for simulating the thermal hydraulic interactions of the High Flux Isotope Reactor (HFIR) core at Oak Ridge National Laboratory (ORNL). The model’s domain consists of a three-dimensional fuel plate and a two-dimensional ... En savoir plus

Calculation of Inductance of Sparsely Wound Toroidal Coils

A. Pokryvailo [1],
[1] Spellman High Voltage Electronics Corporation, Hauppauge, NY, USA

Analytical methods used for inductance calculation of toroidal coils yield large errors in the case of coils sparsely wound on low permeability cores. Numerical field calculations can provide “exact” figures. We have outlined several simulation methods. Simplifications, assumptions, and ... En savoir plus

Glass Transition of ABS in 3D Printing

M. Rahman [1], N. R. Schott [2], L. K. Sadhu [3],
[1] North South University, Dhaka, Bangladesh
[2] Department of Plastics Engineering, University of Massachusetts - Lowell, Lowell, MA, USA
[3] IRays Teknology Ltd., Dhaka, Bangladesh

In a commercial 3D printer head, plastic ribbon passes through a hot nozzle of an extruder to dispense liquid plastic droplets to construct the model. In this paper a 2D axisymmetric model of a 3D head is considered to study the secondary transition change from below the glass ... En savoir plus

N. Rezaii [1], J. P. Mai [1],
[1] JPM Silicon GmbH, Braunschweig, Germany

The JPM Silicon GmbH presents a novel method for the production of solar grade silicon in the microwave oven. This method can specially reduce the energy costs and increase the efficiency of the process. A numerical model is developed which depicts the physical, chemical and ... En savoir plus

Numerical Analysis of the Response of Thick Wires to Extreme Dynamic Electro-Mechanical Loads

R. Cunrath[1], M. Wickert[2]
[1]Fraunhofer EMI, Efringen-Kirchen, Germany
[2]Fraunhofer EMI, Freiburg im Breisgau, Germany

Research at Fraunhofer EMI addresses the response of materials in extreme dynamic loads. Besides mechanical or thermal loads, intense electric pulse currents also represent an extreme dynamic load. Experimentally, metallic samples, mainly thick wires, were electro-mechanically loaded ... En savoir plus

COMSOL Multiphysics® Simulations of Graphene Chemical Vapor Deposition (CVD) Growth

K. M. Al-Shurman[1], H. Naseem[1]
[1]The Institute for Nanoscience & Engineering, University of Arkansas, Fayetteville, AR, USA

Chemical vapor deposition (CVD) is a promising effective method for synthesis of graphene films. CVD graphene film is obtained from hydrocarbon species such as CH4 through complex catalytic chemical reactions on the surface of the catalyst. Therefore, studying the catalytic reaction ...

Mathematical Model for Prediction of Transmission Loss for Clay Brick Walls

J. Ratnieks[1], A. Jakovics[1], J. Klavins[1]
[1]Laboratory for Modeling Technological and Environmental Processes, University of Latvia, Riga, Latvia

A 2D numerical model for determination of sound reduction index is set up in this work. Results are in good agreement in middle and high frequency range when using solid structure approximation. Results are compared with experiment. En savoir plus

Benchmark of COMSOL vs. ROXIE Codes for the Calculation of a Particle Accelerator Quadrupole

I. Rodriguez, and J. L. Munoz
ESS Bilbao
Bilbao, Spain

The field quality requirements of most particle accelerator magnets are very tight and, therefore, very precise simulations are needed to accurately calculate these devices. CERN\'s ROXIE code is widely used as a reference software to calculate normal conducting and superconducting ... En savoir plus
