ON the Numerical Discrete Modeling of a Boundary Value Problem Using an Adaptative Discretization Approach Open
An adaptative discretization approach is proposed to build numerical models of boundary value problems with the discrete element method (DEM). It roughly consists of discretizing a domain with small particles within an area of interest (wh…

Experimental Investigation of Sand Subjected to High Stress Levels in Wet and Dry Conditions Open
This work aimed to understand the mechanical behavior of siliceous and calcareous sand materials under uniaxial confined compression loading at high stress levels. For this purpose, a series of quasi-oedometric compression tests were condu…

Gaussian Mixture Model Based Soil Classification Using Multiple Cone Penetration Tests Open
This study presents an application of the Gaussian mixture (GM) method for soil classification using multiple cone penetration tests (CPT). Compared to the hard clustering methods, the GM model classifies the CPT data by representing the p…

Effect of Horizontal Multidirectional Cyclic Loading on Piles in Sand: A Numerical Analysis Open
Foundations of offshore and nearshore wind energy production systems are subjected to multidirectional and cyclic loads, due to the combined action of wind and waves and in the particular case of mutualized anchor foundations for floating …

Experimental investigation of the mechanical behaviour of soft carbonate rock/grout interfaces for the design of offshore wind turbines Open
Since a few years, in France, the development and construction of offshore wind farms in different sites of the country is investigated. The wind turbines will be installed in soft carbonate rock formations (calcarenite, limestone), the me…

Influence of thermal cycles on the deformation of soil-pile interface in energy piles Open
Energy piles are double purpose foundation elements used both for transferring loads to the soil and temperature regulation in buildings. The response of the pile-soil interface is influenced by daily and seasonal temperature variations. I…

Direct interface shear tests on Dunkirk sand Open
After a field test campaign conducted in Dunkirk (north of France) on open-ended steel piles aiming to study the ageing phenomenon, laboratory scale shear tests were designed to study the behaviour of the sand-steel interface. In order to …

Grain kinematics during stress relaxation in sand: not a problem for X-ray imaging Open
X-ray tomography is a very valuable tool for studying the full-field 3D deformation of granular materials. The requirement to stop loading and scan a given state (assumed to be stationary) used in most approaches implies unavoidable stress…

View article: Infrared thermography of rock fracture
Infrared thermography of rock fracture Open
Grain crushing is in part responsible for soil plasticity and dissipates most of the input energy at high stresses. This energy dissipation, as well as the energy dissipated by friction, occurs through heat exchanges. Real-time observation…

Axial behaviour of jacket piles for offshore wind turbines Open
To improve our understanding and to quantify the behaviour of a jacket foundation for offshore wind turbines, several tests have been conducted using a geotechnical centrifuge at 100g. The monotonic tension and compression tests carried ou…
