Birth and ascent of buoyant hydraulic fractures

Brice Tanguy Alphonse Lecampion, Andreas Möri

Hydraulic fracturing treatments are often used in petroleum and other industries to increase the permeability of rock formations and occur naturally as magmatic intrusions. The resulting fractures, propagating perpendicularly to the minimum in-situ stress ...

Gravitational effects on theemergence,propagation,andarrestofhydraulicfractures

Brice Tanguy Alphonse Lecampion, Andreas Möri, Carlo Peruzzo, Dmitriy Garagash

Hydraulic fractures are driven by an internal fluid pressure exceeding the minimum compres- sive 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 develo ...

Propagation of planar three-dimensional buoyant hydraulic fractures

Andreas Möri

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 ...

Analytical Studies in Support of an Improved Approach to the Design of Acceleration-Sensitive Nonstructural Elements

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady

This paper summarizes a series of analytical studies that were conducted in connection with an improved approach for the design of acceleration-sensitive nonstructural elements. In the new approach, bracing to secure nonstructural elements to the structure ...

Estimating the non-dimensional energy of vortex rings by modelling their roll-up

Karen Ann J Mulleners

The non-dimensional energy of starting vortex rings typically converges to values around 0.33 when they are created by a piston-cylinder or a bluff body translating at a constant speed. To explore the limits of the universality of this value and to analyse ...

Measurement and comparison of graphene-based resonant accelerometers

Driss Belkass

An accelerometer is a device used to measure acceleration. Acceleration is the rate of change of an object’s velocity, measured in square meters per second [m/s2] or g force. This type of device is used to detect vibrations or the orientation of certain sy ...

Proof Of Concept Of A Graphene-Based Resonant Accelerometer

Luis Guillermo Villanueva Torrijo, Daniel Moreno Garcia

Acceleration measurements are fundamental in applications such as consumer electronics, navigation, automotive safety and Internet of things (IoT). In comparison with capacitive or piezoresistive MEMS accelerometers, resonant graphene accelerometers have t ...
