Applications are welcomed for two PhD positions in Navier Laboratory (Ecole des Ponts ParisTech, Univ. Gustave Eiffel, CNRS) on geomechanical modeling for application to nuclear waste storage. The first topic aims at investigating the role of bound water on the THM couplings of claystone, the second topic is dedicated to fluid-induced cracking in fractured claystone. Candidates must hold a Master of Science or equivalent in mechanics and physics of (geo)-materials with a strong taste for numerical modeling.

The University of Calgary, the University of La Rochelle and INRAE are pleased to invite applications for a PhD position (3 years) to model the mechanical behavior of granular materials subjected to cyclic hydraulic loading and to analyze the induced instabilities. This PhD project is part of the StabDigue project supported by the French Region Nouvelle Aquitaine on the analysis of both the stability and durability of dikes and retaining structures along the coastline. The PhD candidate will benefit from both a French-Canadian double PhD degree and the International Research Network Multi-Physics and Multi-scale Couplings in Geo-environmental Mechanics (GDRI CNRS GeoMech).

Three new PhD positions are open in the University of Southampton, UK.

 1) Mathematical Modelling of Poro-Mechanics of Soil (Tiina Roose and William Powrie) – This project will investigate how the degree soil water saturation influences soil mechanics, particularly the non-uniformity of moisture content distribution within the soil, which becomes more significant as the range of grain sizes increases. We aim to develop new mathematical model where the role of plants in soil mechanics can be included, which relates to the effects of spatially and temporally heterogeneous wetting and drying cycles on the soil matrix.

A new PhD position is open in Grenoble (3SR in collaboration with Lafarge/Holcim and ILL/ ESRF) in France. The project aims at studying the chemo-hydro-mechanical behaviour of cement paste during carbonation in the context of C02 sequestration in recycled aggregates.
The technical strategy is to benefit from recent development in terms of bi-modal imaging (X-rays and Neutron) to investigated in real-time the C02 reaction with cement paste. Development of the chemical part of a fully coupled thermo-hydro-chemo-mechanical models is also planned to optimize the industrial process of C02 sequestration to reach carbon neutrality of cement industry.

A new PhD position is open at the Université Gustave Eiffel, France. The project will focus on the investigate the influence of ground liquefaction on the behavior of homogeneous embankment under seismic loading. The technical strategy of this study will be a combined approach of 70% physical centrifuge modeling and 30% numerical modeling. The experimental study will provide important proof on the physical phenomena and essential data for numerical modeling; Being the complimentary of experimental work, the calibrated numerical model will be used to carry out parametric and case studies.  Based on the experimental and numerical work, possible remediation strategies could be proposed, which could be helpful for the construction of embankment-type geo-structures in the industrial sector.

Application closing date: April 15, 2020

Applications are invited for an Assistant or Associate Professor of Experimental Soil Mechanics. The position is proposed to improve our understanding of the fundamental mechanical behaviour of soils undergoing ageing and cyclic environmental loads, and to provide new solutions to the present and future challenges of the built environment. The focus is on developing new experimental techniques and strategies to better understand and tune the response of soils to increasingly high (time-dependent and dynamic) loadings. Emerging sensor and imaging technologies offer the opportunity to develop a new generation of experimental techniques for soil testing in the laboratory and in the field.

The closing date for applications is 15 March 2020.

Fed up with polluted skies? Looking forward to sunny days? Contribute with your research to address one of the major challenges of the XXI century: achieving zero emissions to enjoy the blue sky again. We offer a 3-year PhD position for modeling induced post-injection seismicity as a result of fluid injection/extraction related to geothermal energy, geologic carbon storage and subsurface energy storage. The position is related to the ERC-StG project GEoREST (predictinG EaRthquakES induced by fluid injecTion) (www.georest.eu), funded by the European Research Council (ERC, https://erc.europa.eu/). The candidate will perform her/his research at the Spanish National Research Council (CSIC) in a collaborative and enthusiastic environment.

A new PhD position on soil and structural mechanics is open at the BAM in Berlin. The project will study the buckling phenomena and soil-structure interaction of large-diameter offshore piles during installation and service, with a special focus on the critical conditions for pile-tip buckling, buckle propagation during driving and general buckling limits of the embedded pile during service.

Multi-scale behaviour and damage of heterogeneous rocks around underground excavations.

Link to description

The goal of this project is to investigate the multi-scale behaviour of clay rock, going from microscopic to macroscopic scale. The research will be based on multi-scale approach and numerical method allowing to model microstructure media in a double-scale framework (FEMxFEM).

Applications are welcome from PhDs graduated in the areas of civil, mechanical, and materials engineering, or geosciences. PhDs in geomechanics / geotechnics are mostly welcome.

Applications should be submitted before the end of April 2020
