Non Linear Mechanical and Poromechanical Analyses: Comparison with Analytical Solutions

M. Souley, and A. Thoraval
INERIS
Ecole des Mines
Parc de Saurupt, France

The long-term behaviour of the underground excavations is a social and economic challenge particularly in the contexts of post-mining or radioactive waste storage. Numerical modelings are currently used to understand and forecast the complex behaviour of rock mass around the underground ... Read More

Fluid Structure Interaction Applied to Upper Aorta Blood Flow

J. Anza[1], and M. Esteves[2]
[1]Department of applied mathematics, University of the Basque Country, Bilbao, Spain
[2]University of the Basque Country, Bilbao, Spain

This work deals with the computer simulation of the blood flow, the arterial wall deformation and their 3D bidirectional interaction, including initial stresses and root displacements. The flow is laminar and steady with flexible walls modeled with a hyperelastic Demiray material model. ... Read More

The Campi Flegrei Deep Drilling Project ‘CFDDP’: Understanding the Magma-water Interplay at Large Calderas

G. De Natale[1], G. Perillo[2], C. Troise[1], and P. Gasparini[3]
[1]INGV-Osservatorio Vesuviano, Naples, Italy
[2]Università degli Studi di Napoli Parthenope, Naples, Italy
[3]AMRA scarl, Naples, Italy

Campi Flegrei caldera is a good example of the most explosive volcanism on the Earth, a potential source of global catastrophes. It has the advantage that the most interesting structural details and main volcanic features appear located at shallower depth, making it a natural candidate ... Read More

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 ... Read More

Development of Mathematical Model for Determining Sound Reduction Index of Building Elements

J. Ratnieks, A. Jakovics, and J. Klavins
University of Latvia
Riga, Latvia

Although we know the physics inside a media where the sound waves propagate, determination of material\'s or structure\'s sound reduction index is not an easy task. The lack of good engineering solutions proves the point. The only reliable way to calculate the sound reduction index is ... Read More

Impulsive Thermomechanics of hypersonic surface phononic crystals

F. Banfi[1], D. Nardi[2], and M. Travagliati[3]
[1]Dipartimento Matematica e Fisica, Università Cattolica, Brescia, Italy
[2]JILA, University of Colorado at Boulder, Boulder, Colorado, United States
[3]Center for Nanotechnology Innovation @NEST, Istituto Italiano di Tecnologia, Pisa, Italy

Ultrafast optical generation of pseudosurface acoustic waves is investigated in hypersonic surface phononic crystals. The thermomechanics is modeled from first-principles to follow the initial impulsive heat-driven displacement in the time domain. Spectral decomposition of the ... Read More

Electromagnet Shape Optimization using Improved Discrete Particle Swarm Optimization (IDPSO)

R. S. Wadhwa[1], T. Lien[1], and G. Monkman[2]
[1]NTNU Valgrinda, Inst. for produksjons- og kvalitetstek., Trondheim, Norway
[2]FH Regensburg, Regensburg, Germany

The magnetic field gradient produced by an electromagnet gripper head depends on its design. Stochastic Methods offer certain robustness to the design optimization process. In this paper, Improved Discrete Particle Swarm Optimization (IDPSO) searching technique is applied to the shape ... Read More

Objects in a Windtunnel Simulated With COMSOL

H. van Halewijn
Fontys Hogeschool
Applied Physics
Eindhoven, The Netherlands

For the educational program of Fluid Dynamics at the Fontys Hogeshool of Applied Physics, a wind tunnel was developed for tests of flow profiles of objects, such as a ball, cube or plate. Students are expected to measure the air resistance of a variety of objects, and verify the ... Read More

Electro-acoustic Coupling in Nematic Liquid Crystals

G. Rosi[1], L. Teresi[1], A. DiCarlo[1], and F. dell'Isola[2]
[1]LaMS - Università degli Studi Roma Tre, Roma, Italy
[2]Università degli Studi di Roma "La Sapienza", Roma, Italy

Liquid crystals - as all liquids - are generally modelled as incompressible media. In fact, mass-density changes occurring in these mesophases are minuscule and inconsequential in most regimes of interest. However, liquid crystals exhibit also phenomena that call for a more refined ... Read More

Study of Gas Dynamics in the Heat-accumulation Stoves

P. Scotton, and D. Rossi
Dipartimento di geoscienze
Università di Padova
Padova, Italy

The paper aims to clarify some aspects of the gases hydro-dynamics within the twisted conduct of heat accumulation stoves (ceramic-refractory stoves) downstream the combustion chamber. Both Comsol laminar and k-e turbulent models have been used in case of straight and curved pipes with ... Read More
