key words : Discrete Element Method, Ceramic Material, Dynamic Shock

This thesis aims to make a significant advance in the modeling of fracture behaviors occurring in ceramics against high and short loadings. Laser shock will be specifically studied and will be the main application in this work. The dynamic behavior of such ceramics are currently modeled with homogenized techniques and are limited when fracture occurs. In this thesis, the Discrete Element Method (DEM) will be investigated to simulate a laser shock. Complex fracture behavior such as initiation, rapid propagation and coalescence must be obtained and validated with experimental datas at the CEA. The DEM is also developed for more than ten years at the Institute of Mechanics and Engineering of Bordeaux especially in the simulation of brittle materials.

Working within the Department of Mechanical and Construction Engineering, you will provide expertise in an area of Civil Engineering to further enhance research, teaching and entrepreneurial activities. The department has particular strengths in Civil Engineering Heritage, Future Construction Technology, and Construction Engineering Management. We are currently seeking to strengthen and consolidate our existing activity in Civil Engineering. In particular, we are looking for candidates with research expertise in fire and explosion resistance of structures, but welcome applications from candidates across all of our areas of research, which include: numerical geotechnics; highway materials; numerical modelling of water and environmental chemistry; railway infrastructure.

Project Description
It is well understood that microscopic interactions between water menisci and soil particles govern the macroscopic mechanical behaviour of unsaturated soils. However, how water repellency affects those interactions is largely unknown. Successfully accounting for the effect of repellency on soil hydro-mechanical behaviour could yield significant benefits to geotechnical design. Soil water repellency naturally arises due to the deposition of plant oils or humic substances or after severe heating episodes, for example wildfires. Artificial treatments can, however, also be used to render soils permanently hydrophobic. Such treatment might be desirable to deter infiltration, for example in engineered cover systems where waste exposure to water may result in severe contamination of the surrounding landscape.
This project will exploit state-of-the-art experimental techniques to examine the evolution of water-repellent soil hydro-mechanical behaviour on the microstructural (water retention and pore size evolution) and macrostructural (strength and stiffness) scales. The project will take advantage of the long-term strong collaborative relationships between leading UK universities studying unsaturated soil behaviour to deliver an engaging and rewarding PhD experience.

Applications are welcome for a PhD position to investigate the dynamic impact of construction works on neighboring freshly installed concrete structures within the soil (e.g. piles). The research will focus on numerical and experimental investigations with focus on geodynamics. The project is available to candidates holding a master degree (M.Sc.) in civil engineering, geotechnical engineering, earth science or similar.
Strong interest and experience in numerical methods in geomechanics, constitutive modelling and/or soil dynamics are advantageous. The candidate should have very good knowledge in English (writing/reading/speaking). German language skills are eligible.

Applications are welcome for a PhD position to investigate the response of soils subjected to variations of temperature and water flow conditions through an experimental campaign involving both conventional and state-of-the-art laboratory testing. The project is available to all students, whether home, EU or overseas. The successful candidate should possess at minimum a masters and undergraduate degree in civil engineering, geotechnical engineering, earth science or a similar field. Strong interest and experience on experimental soil mechanics is an essential requirement of this project. The PhD student will get full access to the state-of-the-art facilities of the Geotechnical and GeoMaterials Laboratory at Heriot-Watt University, which includes equipment for unsaturated soil testing (e.g. unsaturated triaxial, oedometer and direct shear apparatus, pressure cells, temperature & environmental chambers) as well as standard geotechnical testing.

The closing date for the applications is October 21^st, 2019.

Applications are invited for a post-doctoral researcher in computational modelling of gas-induced fractures in low-permeability porous media. The post-doctoral researcher will push the boundaries of existing understanding of coupling between gas flow in low permeability porous media and fracturing process, through the development of theoretical models and numerical tools. It is anticipated that the researcher will need to develop models which include discrete pathways in a heterogeneous (continuum) material. Challenges exist in simulating the development of the discrete pathways and the impact of the heterogeneity on the macroscopic behaviour. The simulation tools developed will be based on existing finite element tools for multiphase flow and mechanics, which require novel additions to include discrete pathways. Close collaboration with experimentalists is expected.

The closing date for applications is 11^th October 2019.
