The University of Glasgow currently has an exciting opportunity for a Research Associate (postdoc) to make a leading contribution to an EPSRC-funded project with Dr Junlong Shang. The INFORM project will examine the influence of fracture heterogeneity on the integrity and deformation behaviour of rocks across scales using experiment and modelling approaches, with a goal of sustainable geological disposal of radioactive waste. The project involves a significant programme of laboratory (direct shear, triaxial deformation), field (rock sample and fracture data collection), and modelling (DEM) study as well as engagement with our national and international academic and industry partners. The successful candidate will also be expected to contribute to the formulation and submission of high-quality research publications and research grant proposals.

Come and join UofG to make leading contributions to radioactive waste disposal and global net zero transitions.

– Application deadline: 28 September 2022
– Expected start date: 1 Feb 2023
– As an EPSRC-funded project, UofG can support Global Talent Visa for the successful candidate (if needed), who will be eligible for UK permanent residence after 36 months of working on the project.

The deadline for applications to the position presented in the post below is now extended to the 12th of September, 2022.

Within the Civil Engineering Department, the Hydraulics & Geotechnics Section (Campus Bruges, Faculty of Engineering Technology) and the Structural Mechanics Section (Campus Arenberg, Faculty of Engineering Technology) are currently seeking to recruit a highly enthusiastic and motivated person to pursue full-time doctoral studies in the field of dynamic Soil-Structure-Interaction. The sections are already collaborating in research projects including foundations for offshore wind turbines and floating energy converters, pile driving and installation techniques by means of theoretical developments and experimental approaches. Regarding the later, both sections are part of a collaborative national research project which aims to establish a testing site for pile foundations in Belgium.

Are you interested in deriving elegant, insightful, novel benchmark solutions for a wide range of typical complex SSI problems, and develop a step-change in the way software for SSI is implemented?

End of application: 5 September 2022

The Geotechnics Research Group (GRG) in the Division of Geology and Geotechnics primarily focuses on modelling and characterisation of complex geomaterials, such as naturals and stabilised soils. The research activities aim to bridge fundamental understanding and advanced modelling & testing capabilities with application in engineering practice. GRG has become an internationally recognised group in experimental testing and modelling at laboratory and field scale.

We are looking for a highly motivated individual to fill a post-doc position linked with a research project funded by Formas (Swedish research council), which aims is to develop a multi-physics model to assess the impact of climate change on the built environment in terms of stability and ground movements. A major component will be the development of an efficient scalable computational framework for multiphysics modelling of geostructures in FEniCSx, accounting for the spatial heterogeneity of the soil and the probabilistic nature of the environmental loading on its interfaces (atmosphere, lower and upper aquifer). In addition to the main supervisor (Prof. Minna Karstunen), the post-doc is supported by Dr Ayman Abed and Prof. Jelke Dijkstra. The project is part of a larger constellation of projects that focus on modelling the impacts of climate change and mitigation measures and liked with the activities of Digital Twin Cities Centre at Chalmers.

Title: Rheology and transport properties of rock salt: application to salt cavern storage

Research outline: The PhD candidate will work in the framework of the ANR RockStorHy project, which investigates the rheology and the transport properties of rock salt (in particular, tightness to gases stored in the context of the energy transition).
Several PhD students and French research laboratories will collaborate in the project. A major outcome of this PhD work is to propose a unified constitutive law covering a wide range of stress ranges, which will be fit against the quantitative results of macroscopic tests and the qualitative lessons drawn from microscopic analysis conducted during the project. Transport properties will be examined at the micro and macro-scales (experimental and numerical work). Numerical computations at the cavern scale will be performed using, for comparison, several standard constitutive laws and the unified law resulting from the experimental efforts. Emphasis will be put on cycled operation of hydrogen storage caverns.

Keywords : rock salt, rheology, underground storage, energy transition

Prequisite skills and knowledge:

• Continuum solid mechanics
• Strong background in mathematics
• Knowledge of the finite element method (modeling experience if possible)
• Willingness to perform experimental work on rocks
• Fluent in English and French (oral, spoken, written)
• Eager to work in a multidisciplinary environment

Contact: laura.blanco_martin@minesparis.psl.eu

Starting date: not later than January 2, 2023 (grant is for 36 months)

Deadline for applications: September 23, 2022

Please send your application as one pdf file including: CV, letter of motivation, two recommendation letters, bachelor and master grades

“Multi-scale approach to study the effect of fines content and particle shape on static liquefaction potential of loose mine tailings”

Mine tailings are silty sand slurries deposited by hydraulic filling in storage facilities, where the material remains saturated, loose, and might be liquefiable causing catastrophic mudflows. Empirical evidence shows that intrinsic material parameters, such as characteristic particle size, particle size distribution, and non-plastic fines content, could significantly affect the tailing liquefaction potential. However, it remains unclear what are key elements and physical mechanisms at the source of these observations. The main objective is to develop a general multi-scale framework to assess the static liquefaction potential of loose tailings as a function of fines content and grain shape, based on experimental testing and numerical DEM simulations.

We offer a fully-funded 4-year PhD position, as part of a collaboration between academic institutions, Polytechnique Montréal (Canada) and Université de Montpellier (France), and industrial partners SRK Consulting (Canada) and Peñoles Mining Company (Mexico).

Candidates must have experience with numerical modeling of materials. Experience with experimental set-up and testing of geomaterials, although not necessary, is highly appreciated. Programming skills with python are essential. Students having a Mechanical/Civil Engineering or Physics background are invited to apply.

We invite the candidates to send a detailed CV (including the contact details for 2 references), a motivation letter and Bachelor and Master transcripts to Prof. Carlos Ovalle (carlos.ovalle@polymtl.ca) & Prof. Emilien Azéma (emilien.azema@umontpellier.fr).

Note: The recruitment process will ensure that the principles of equity, diversity and inclusion are respected, and in the case of equal skills among candidates, preference will be given to the recruitment of women, underrepresented minorities, and individuals with disabilities.
