Non Linear Mechanical and Poromechanical Analyses: Comparison with Analytical Solutions
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 ... Per saperne di più
Fluid Structure Interaction Applied to Upper Aorta Blood Flow
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. ... Per saperne di più
The Campi Flegrei Deep Drilling Project ‘CFDDP’: Understanding the Magma-water Interplay at Large Calderas
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 ... Per saperne di più
Influence of Vickers Indenter Tip Geometry on the Macro-indentation Properties of TiAl Alloys
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 ...

Development of Mathematical Model for Determining Sound Reduction Index of Building Elements
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 ... Per saperne di più
Impulsive Thermomechanics of hypersonic surface phononic crystals
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 ... Per saperne di più
Electromagnet Shape Optimization using Improved Discrete Particle Swarm Optimization (IDPSO)
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 ... Per saperne di più
Objects in a Windtunnel Simulated With COMSOL
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 ... Per saperne di più
Electro-acoustic Coupling in Nematic Liquid Crystals
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 ... Per saperne di più
Study of Gas Dynamics in the Heat-accumulation Stoves
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 ... Per saperne di più
