Hydraulic fracturing
Brice Tanguy Alphonse Lecampion
Method and apparatus for monitoring growth of fracture during hydraulic fracturing treatment of a ground formation. A series of tiltmeters are positioned at spaced apart tiltmeter stations at which tilt changes due to hydraulic fracturing treatment are mea ...
2006Meshless animation of fracturing solids
We present a new meshless animation framework for elastic and plastic materials that fracture. Central to our method is a highly dynamic surface and volume sampling method that supports arbitrary crack initiation, propagation, and termination, while avoidi ...
2005Stabilized Crouzeix-Raviart element for the Darcy-Stokes problem
We stabilize the nonconforming Crouzeix-Raviart element for the Darcy-Stokes problem with terms motivated by a discontinuous Galerkin approach. Convergence of the method is shown, also in the limit of vanishing viscosity. Finally, some numerical examples v ...
2005Microdeformation and Fracture in Bulk Polyolefins
The fracture properties and microdeformation behaviour and their correlation with structure in commercial bulk polyolefins are reviewed. Emphasis is on crack-tip deformation mechanisms and on regimes of direct practical interest, namely slow crack growth i ...
2004Crazing and fracture in polymers. micromechanisms and effect of molecular variables
The influence of the primary molecular parameters chain configuration, architecture and molecular weight (MW) on the mode of mechanical breakdown is discussed for two series of (amorphous) thermoplastic polymers, methyl methacrylate glutarimide copolymers ...
2004Mapping of hydraulic fractures from tiltmeter measurements
Brice Tanguy Alphonse Lecampion
In considering the problem of inverse modeling of tiltmeter data for hydraulic fracture mapping, we address the issues of selecting the elastic model to represent the hydraulic fracture and limitations imposed by distance and fracture size on the informati ...
2003Fracture and toughening of high volume fraction ceramic particle reinforced metals
This work contributes to the fundamental understanding of fracture properties of Particle Reinforced Metal Matrix Composites (PRMMCs), by identifying the key microstructural parameters that control fracture. To this end, PRMMCs with a high volume fraction ...
EPFL2003Crack growth across colony boundaries in binary lamellar TiAl
The crack growth across a boundary between two colonies, i.e. regions of differing lamellar orientation, in two-phase lamellar Ti-Al is studied computationally to quantify the influence of such boundaries on toughening, as observed in recent in-situ fractu ...
