Institute of Hydro-Engineering of the Polish Academy of Sciences announces a competition for the National Science Centre scholarship in the research project Multi-scale study of the contact force network in cohesionless granular materials, no 2020/39/B/ST8/01685.
The main goal of the project is to unravel and classify the characteristic force network structures within 3D and pseudo - 2D granular packings. The integrated photo-elasticity, image processing and tomographic software are planned to be employed. Parallel use of DEM source code will be used to recreate the selected macro characteristics of the real sample, such as the grain distribution curve and the initial porosity, or in some cases, the exact structure of the grains' arrangement. To make the research on force networks complete, the corresponding deformation states need to be studied. DIC and DVC software will be used to calculate displacement and strain fields of experimental and numerical samples.
The specific problems to be addressed in this project are: photo-elastic optical tomography for granular materials, application of 2D Fourier transforms for scale definition, separation of the force network from the grain network, localization phenomenon in contact force networks and its relation to strain localization, characteristics of force chains in two-dimensional (2D), pseudo-2D and three-dimensional (3D) grain assemblies, individual grains behaviour inside shear bands.
The candidate has to meet the following requirements:
- first-year (2021/22) student at the Doctoral School at Gdansk University of Technology, assigned to the discipline Civil Engineering and Transport,
- knowledge of the problems of photo-elastic techniques in application to granular materials,
- strong motivation for scientific work, willingness to acquire new knowledge and skills,
- ready to conduct labor-intensive experimental research and complex numerical simulations,
- good command of spoken and written English.
Nature of contribution to the project: scholarship grantee
Specific tasks planned for the candidate in the project (Scope of work):
- 3D experimental analysis of force network structure in granular materials,
- participation in creating 3D photo-elastic test equipment and experimental program,
- 3D numerical simulations by DEM method,
- analysis of results,
- attending the doctoral school at Gdańsk Technical University, co-run by IBW PAN.
