Expansive soil has wide application in industry and research. An example includes compacted bentonite which can be used in landfill cover and as a buffer barrier in nuclear deep geological deposition.
If these materials undergo desiccation, it can experience a significant volume decrease. This compromises the integrity and function of these geostructures, threatening their safety and reliability.
In this project, we'll study molecular dynamics to investigate the underlying mechanism of bentonite's behaviour during drying and provide guidance for material improvement.
As part of the research project, you will:
- conduct comprehensive literature review about the method of molecular dynamics and its current applications in material science
- investigate the potential package of molecular dynamics available for the study in expansive soil
- apply the selected molecular dynamics package to simulate the drying process of bentonite
- discover an approach to improve bentonite's performance when drying, based on molecular dynamics simulations.
Upon completion the research project, we expect to have:
- a comprehensive literature review
- molecular dynamics simulation
- suggestions to improve the performance of bentonite when drying.
