Coupled inverse modeling of a controlled irrigation experiment using multiple hydro-geophysical data

Gabriele Manoli, Damiano Pasetto, Matteo Rossi

Geophysical surveys can provide useful, albeit indirect, information on vadose zone processes. However, the ability to provide a quantitative description of the subsurface hydrological phenomena requires to fully integrate geophysical data into hydrologica ...

The role of elastic waves during dynamic rupture of heterogeneous interfaces

Jean-François Molinari, Fabian Barras

Along a planar interface bonding two solids made of Homalite, we simulate rupture events in the presence of a unique tougher inclusion with insights on the influence of its geometry and fracture properties. Our study is then pursued with fracture planes ma ...

High Performance Computing Simulations of Dynamic Fragmentation in Brittle Materials

Marco Vocialta

The aim of this thesis is to investigate the mechanisms behind dynamic fragmentation. This phenomenon occurs in a material when a blast or impact loading nucleates multiple cracks, whose propagation and coalescence break the specimen into fragments. Althou ...

Isogeometric numerical dispersion analysis for two-dimensional elastic wave propagation

Alfio Quarteroni, Luca Dede', Christoph Jäggli

In this paper, we carry out a numerical dispersion analysis for the linear two-dimensional elastodynamics equations approximated by means of NURBS-based Isogeometric Analysis in the framework of the Galerkin method; specifically, we consider the analysis o ...

Seismic Behaviour and Design of Mixed RC-URM Wall Structures

Alessandro Paparo

In several countries of central Europe, many modern residential buildings are braced by reinforced concrete (RC) and unreinforced masonry (URM) walls coupled with RC slabs. Such mixed constructions, in fact, behave better under seismic loading than buildin ...

Frequency-dependent, near-pole behavior of acoustic surface waves on a solid sphere

Alessandro Spadoni, Bart Van Damme

A laser vibrometer is used to measure waves generated by a piezoelectric transducer in a solid steel sphere. The spatial and temporal resolution make it possible to verify the theoretical dispersion relation of spherical surface waves. In particular, the a ...

Role of filling materials in a P-wave interaction with a rock fracture

Jian Zhao, Wei Wu

The purpose of this study is to investigate the role of filling materials (e.g., quartz sand and kaolin clay) in the interaction between a P-wave and a rock fracture. The specific fracture stiffness reflects the seismic response of a filled fracture, while ...

Elastodynamics of a Two-Dimensional Square Lattice With Entrained Fluid-Part I: Comparison With Biot's Theory

Alessandro Spadoni, Vladimir Dorodnitsyn

In the present paper, the performance of Biot's theory is investigated for wave propagation in cellular and porous solids with entrained fluid for configurations with well-known drained (no fluid) mechanical properties. Cellular solids differ from porous s ...

Calcarenite as a possible host rock for CO2 sequestration

Roman Makhnenko

Deep saline aquifers have a great potential for geologic carbon dioxide (CO2) sequestration and proper assessment of host and cap rock is needed to guarantee that the procedure is safe. Temperatures and pressures at which most of the possible host rocks ex ...

Cloaking and invisibility: A review

Romain Christophe Rémy Fleury

Invisibility has been a tantalizing concept for mankind over several centuries. With recent developments in metamaterial science and nanotechnology, the possibility of cloaking objects to incoming electromagnetic radiation has been escaping the realm of sc ...
