MATHEGRAM: Multiscale analysis of thermomechanical behaviour of granular materials
MATHEGRAM: Multiscale analysis of thermomechanical behaviour of granular materials
MATHEGRAM was an Initial Training Network funded by the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement MATHEGRAM No 813202. This was multidisciplinary and inter-sectoral consortium consisting of 10 leading academic and non-academic beneficiaries from six EU countries. The project was led by Prof. Charley Wu, University of Surrey.
At Imperial College the team members were:
- Marina Bortolotto (ESR6)
- Dr. Tokio Morimoto (ESR7). (Dr. Morimoto is now based at the University of Tokyo, Japan.).
Marina Bortolotto has worked to:
- Understand the link between thermal changes at the particle scale and overall thermo-mechanical response of granular media through thermal characterisation experiments in a controlled-stress environment
- Develop a dataset suited to validation of thermal particulate DEM codes.
Tokio Morimoto worked to:
- Perform DEM modelling of thermal triaxial tests and to advance understanding of the link between contact configurations and thermal performance of granular materials
- Simulate tests on model granular materials
- Explore the sensitivity of thermal response to fabric and packing configuration.
