Fully-coupled 3D modelling of magmatic dike Propagation – finite pulse release from a point source

Brice Tanguy Alphonse Lecampion, Andreas Möri, Haseeb Zia

Magmatic dikes are a naturally occurring type of fluid-driven fractures [1] propagating in the lithosphere driven by buoyancy (more precisely by the difference between the in-situ minimum horizontal stress gradient and the magma weight). Fully-coupled mode ...

Modeling of Simultaneous Propagation of Multiple Blade‑Like Hydraulic Fractures from a Horizontal Well

Brice Tanguy Alphonse Lecampion, Dmitry Nikolskiy

We explore different aspects of the multi-stage fracturing process such as stress interaction between growing hydraulic fractures, perforation friction, as well as the wellbore flow dynamics using a specifically developed numerical solver. In particular, g ...

Explicit versus implicit front advancing schemes for the simulation of hydraulic fracture growth

Brice Tanguy Alphonse Lecampion, Haseeb Zia

The proper computation of the time evolution of the fracture front is the main challenge of three-dimensional (3D) hydraulic fracture growth simulation. We discuss explicit and implicit variants of a hydraulic fracture propagation scheme based on a level s ...

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 ...

Impact of the anisotropy of fracture toughness on the propagation of planar 3D hydraulic fracture

Brice Tanguy Alphonse Lecampion, Haseeb Zia, Weihan Zhang

Sedimentary rocks often exhibit a transverse isotropy due to fine scale layering. We investigate the effect of the anisotropy of fracture toughness on the propagation of a planar 3D hydraulic fracture perpendicular to the isotropy plane: a configuration co ...

Cyclic loading of a cellulose/hydrogel composite increases its fracture strength

Dominique Pioletti, Pierre-Etienne Bourban, Peyman Karami, Céline Samira Wyss

The fracture properties of hydrogels which present similar characteristics to the Mullins effect is expected to decrease under repeated cyclic loading. Therefore, we assessed how cyclic loading affects the fracture behavior, the distribution of strain fiel ...

Fatigue as the missing link between bone fragility and fracture

Dominique Pioletti, Vincent Stadelmann, Claire Acevedo

The prevention of fragility fractures in bone—pathologic fractures resulting from daily activity and mostly occurring in the elderly population—has been a long-term clinical quest. Recent research indicating that falls in the elderly might be the conse- qu ...

Evolution of the tensile properties of the tempered martensitic steel Eurofer97 after spallation irradiation at SINQ

Philippe Spätig, Hans-Peter Seifert, Yong Dai, Serafin Knitel

Small disk tensile specimens of the reduced activation tempered martensitic steel Eurofer97 were tested from −100 °C up to 370 °C before and after irradiation in the spallation source SINQ at Paul Scherrer Institute. The calculated irradiation dose and hel ...
