Poro-mechanics is a branch of mechanics considering the hydro-mechanical behaviour of a porous solid medium whose pores are saturated by a fluid. The presence of both these constituents significantly influences the overall macro-response of the mater...

The ability to model rigid body interaction with highly deformable solids is a very useful tool in geoengineering, including the modelling of drag anchors on seabeds and seabed ploughing [7, 1]. However, these simulations entail several numerical cha... Read More about Dynamic three-dimensional rigid body interaction with highly deformable solids, a material point approach.

Cone penetration tests (CPTs) in bi-phase soils: A material point approach with rigid body interaction (2023)
Presentation / Conference Contribution
Bird, R., Pretti, G., Coombs, W. M., Augarde, C. E., Sharif, Y., Brown, M., …Johnson, K. (2023, April). Cone penetration tests (CPTs) in bi-phase soils: A material point approach with rigid body interaction. Paper presented at UK Association for Computational Mechanics 2023 (UKACM 2023), University of Warwick, UK

Cone Penetration Tests (CPTs) can be used to determine in-situ material properties and represent a practical choice for site investigation offshore, especially for linear infrastructure, such as Offshore Wind export cables. Information gained from CP... Read More about Cone penetration tests (CPTs) in bi-phase soils: A material point approach with rigid body interaction.

A comparison of approaches for modelling poro-mechanics in the Material Point Method (2022)
Presentation / Conference Contribution
Pretti, G., Coombs, W., & Augarde, C. (2022, April). A comparison of approaches for modelling poro-mechanics in the Material Point Method. Paper presented at UKACM 2022, Nottingham, UK

When it comes to the analysis of fully saturated porous materials, a plethora of formulations [1] are available in the literature. Among them, the so-called u − p formulation constitutes a well-established approach when low-frequency problems are con...
