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 ...

Steadily Moving Semi-Infinite Hydraulic Fracture in a Poroelastic Media

Brice Tanguy Alphonse Lecampion, Andreas Möri

Linear elastic fracture mechanics has been widely used to describe the propagation of hydraulic fractures in rocks [1]. The embedding material is generally considered to be elastic and permeable, but the fluid exchange between the fracture and the media is ...

Hydraulic fracture growth in quasi-brittle materials

Dong Liu

Hydraulic fracturing is a technique often used in the oil and gas industry to enhance the production of wells in low-permeability reservoirs. It consists of fluid injection at a sufficiently large injection rate to create and propagate tensile fractures in ...

Multi-scale modeling of aggregate interlock phenomena in concrete

Mohit Pundir

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 ...

Time-lapse reconstruction of the fracture front from diffracted waves arrivals in laboratory hydraulic fracture experiments

Brice Tanguy Alphonse Lecampion, Dong Liu, Thomas Emmanuel Blum

4-D acoustic imaging via an array of 32 sources/32 receivers is used to monitor hydraulic fracture (HF) propagating in a 250 mm cubic specimen under a true-triaxial state of stress. We present a method based on the arrivals of diffracted waves to reconstru ...

Planar hydraulic fracture growth perpendicular to the isotropy plane in a transversely isotropic material

Brice Tanguy Alphonse Lecampion, Haseeb Zia, Fatima-Ezzahra Moukhtari

The configuration of a hydraulic fracture (HF) propagating perpendicular to the isotropy plane of a transversely isotropic (TI) material is encountered in most sedimentary basins. We account for both elastic and fracture toughness anisotropy, and investiga ...

Porous granules by freeze granulation of Pickering emulsions stabilized with halloysite particles

Paul Bowen

Pickering emulsions stabilized with a natural silicate mineral, halloysite, were dried by freeze granulation in order to prepare porous granules. Different formulations were studied, by varying the pH of the suspension, the ionic strength and with the addi ...

Influence of curved delamination front on R-curve of DCB specimen

Thomas Keller, Anastasios Vassilopoulos, Zhengwen Jiang

This work investigated the evolution of the non-uniform distribution of Mode-I strain energy release rate (SERR) along a straight pre-crack front of double cantilever beams (DCB), caused by the anticlastic deformation and the longitudinal free-edge effects ...

Post-Tensioned Structural Glass Beams - Comparative Experimental Study

Pieter Christian Louter, Jagoda Cupac

This paper presents a study of a system of post-tensioned structural glass beams. In order to increase the initial fracture strength of glass beams and provide residual load-carrying capacity in the event of glass failure, annealed laminated glass beams ar ...

Comparative Study of Post-tensioned Glass Beams with Bonded Tendons

Pieter Christian Louter, Jagoda Cupac

This paper explores the system of laminated annealed glass beams post-tensioned through stainless steel tendons bonded to the lower glass edge. The tendons are first pre-tensioned and then adhesively bonded to the glass. The compressive pre-stress applied ...
