Relevance of correlation length in geotechnical engineering (2024)
Presentation / Conference Contribution
Lloret-Cabot, M., Zhang, K., Zhang, W., & Toll, D. (2024, August). Relevance of correlation length in geotechnical engineering. Presented at Proceedings of the XVIII ECSMGE 2024, Lisboa

Soils are heterogeneous in nature and as such, their properties inherently exhibit a distinct spatial variation that reveals past information of their geological history. This spatial variability is an important source of geotechnical uncertainty and... Read More about Relevance of correlation length in geotechnical engineering.

Mathematical modelling of pressure induced freezing point depression within soils exhibiting strong capillary pressure effect (2024)
Presentation / Conference Contribution
Lgotina, E., Mathias, S., Lloret-Cabot, M., & Ireson, A. (2024, April). Mathematical modelling of pressure induced freezing point depression within soils exhibiting strong capillary pressure effect. Presented at 2024 UK Association for Computational Mechanics Conference, Durham, UK

Many geotechnical applications are affected by the melting and formation of ice in soils. Current state of practice involves incorporating the presence of ice within hydrological models for unsaturated soils using the so-called generalised Clapeyron...

A non-hysteretic simplification to the Glasgow Coupled Model (GCM) (2024)
Presentation / Conference Contribution
Mutsvairo, T., Lloret-Cabot, M., Hughes, P., Muguda-Viswanath, S., & Dias, A. S. (2024, April). A non-hysteretic simplification to the Glasgow Coupled Model (GCM). Presented at 2024 UK Association for Computational Mechanics Conference, Durham, UK

The Glasgow Coupled Model (GCM) is an established elasto-plastic constitutive model developed to capture the coupled hydro-mechanical response of unsaturated soils. This study highlights the unique capabilities of the GCM in modelling the water ret... Read More about A non-hysteretic simplification to the Glasgow Coupled Model (GCM).

Numerical performance of different order explicit integration schemes with substepping and automatic error control (2023)
Presentation / Conference Contribution
