Three-dimensional buoyant hydraulic fractures: finite volume release
Brice Tanguy Alphonse Lecampion, Andreas Möri
In impermeable media, a hydraulic fracture can continue to expand even without additional fluid injection if its volume exceeds the limiting volume of a hydrostatically loaded radial fracture. This limit depends on the mechanical properties of the surround ...
2023Ascent and movement of buoyant fluids in the lithosphere
Brice Tanguy Alphonse Lecampion, Andreas Möri, Carlo Peruzzo
Hydraulic fractures are driven by an internal fluid pressure exceeding the minimum compressive stress, propagating in a direction perpendicular to the latter. This class of tensile fractures has gained interest over the last fifty years due to the developm ...
2023Automatic and high-precision acoustic emission-based structural health monitoring of concrete structures
Acoustic emission (AE) monitoring is a useful technique to monitor the health of a structure continuously, helping to prevent potential failure. AE are elastic waves produced and emitted during fracture processes inside a material and are recorded by senso ...
DESTech publications inc.2023Prediction of crack nucleation and propagation in porous ceramics using the phase-field approach
The relevance of the phase-field approach to simulate the fracture in porous ceramics has been investigated. For this purpose, the conditions for the crack initiation using the phase-field model have been compared to the theoretical predictions of the coup ...
ELSEVIER2022The Permeability of Porous Volcanic Rock Through the Brittle-Ductile Transition
Marie Estelle Solange Violay, Gabriel Gérard Dominique Meyer, Corentin Jean-Marie Rémi Noël, Michael Heap
The permeability of volcanic rock controls the distribution of pore fluids and pore fluid pressure within a volcanic edifice, and is therefore considered to influence eruptive style and volcano deformation. We measured the porosity and permeability of a po ...
AMER GEOPHYSICAL UNION2022Breakdown of Reye's theory in nanoscale wear
Jean-François Molinari, Antonio Joaquin Garcia Suarez, Tobias Brink
Building on an analogy to ductile fracture mechanics, we quantify the size of debris particles created during adhesive wear. Earlier work suggested a linear relation between tangential work and wear debris volume, assuming that the debris size is proportio ...
2022Multi-scale modeling of aggregate interlock phenomena in concrete
In concrete structures, opened cracks contribute significantly to the transfer of shear and normal stresses through the contact forces occurring between fractured surfaces. Such contact forces are due to protruding asperities, engaged by interlocking and f ...
EPFL2021Mixed-mode fracture response of anti-symmetric laminates: Experiments and modelling
Multidirectional laminates are very often used in advanced structures. However, the existing data in the literature regarding their fracture response is not conclusive. In this work, the fracture response of a +45 degrees// -45 degrees interface is investi ...
ELSEVIER SCI LTD2020Thermal influences on macroscale rock damage
Fracture processes in rock have widespread implications in the geohazard, geomorphologic, and civil and mining engineering communities. Propagation of fractures reduces overall rock mass strength, can lead to large-scale gravitational instabilities, and ca ...
2020Laboratory studies of hydraulic fracture growth in quasi-brittle rocks with different grain sizes
Brice Tanguy Alphonse Lecampion, Dong Liu
Well completion for oil and gas, geothermal energy as well as CO2 storage sometimes require stimulation to achieve economical fluid flow rates (for both injector and producer wells). Predicting the growth of fluid-driven fractures in geological systems is ...
