Can a bi-lateral stress jump really arrest the height growth of a hydraulic fracture?

Brice Tanguy Alphonse Lecampion, Carlo Peruzzo, Barnaby Padraig Fryer

In certain industrial applications, vertical growth of hydraulic fractures beyond a targeted formation of interest can cause economic loss and pose a risk to environmentally sensitive layers [1]. In addition, when micro hydraulic fracturing is used to meas ...

Phase transformation induced distortions in red gold alloys

Margaux Nathalie Dominique Larcher

Red gold alloys owe their warm and attractive colour to the combination of gold and copper atoms. Thanks to their good mechanical properties and resistance to corrosion, red gold alloys are used in luxury industries as well as in dentistry. Around the equi ...

Laboratory 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 ...

Creep and stress relaxation of a FeMnSi-based shape memory alloy at low temperatures

Cyril Cayron, Christian Leinenbach

The creep and stress relaxation behavior of a Fe-17Mn-5Si-10Cr-4Ni-1(V,C) (wt%) shape memory alloy at low homologous temperatures (-45 degrees C < T < 50 degrees C) was systematically studied in stress and strain controlled tensile tests. At constant stres ...

Implicit level set scheme to model the propagation of planar 3D hydraulic fractures

Brice Tanguy Alphonse Lecampion, Haseeb Zia

We present a python implementation of the implicit level set algorithm to model propagation of planar hydraulic fractures. This algorithm was first introduced by Peirce & Detournay in (2008). The growth of a fluid driven planar fracture is modelled by coup ...

Use of indentation tests to study the influence of confining stress on rock fragmentation by a TBM cutter

Jian Zhao, Lijun Yin, Hongsu Ma

This paper explores the influence of the confining stress on rock fragmentation under the cutter of tunnel boring machine (TBM) by indentation test. Acoustic emission (AE) system was employed for real-time monitoring the rock fragmentation process during t ...

Hydro-mechanical behaviour of a volcanic ash

Lyesse Laloui, Alessio Ferrari, John Eichenberger

This paper presents experimental analysis and numerical modelling aimed at improved understanding and prediction of the hydro-mechanical behaviour of volcanic ash at various states of saturation. Results from a comprehensive experimental program are presen ...

Neurobiological Mechanisms Involved in the Establishment and Maintenance of Dominance Hierarchies and its Modulation by Stress in Rats

Maria del Carmen Sandi Perez, Marjan Timmer

Stress can have a strong and long lasting effect on the establishment and maintenance of dominance hierarchies in rats. When two rats of a pair have not been stressed (non-stressed pair) before a first social encounter, they establish a dominance hierarchy ...
