A modified CPT based installation torque prediction for large screw piles in sand (2018)
Presentation / Conference Contribution
Davidson, C., Al-Baghdadi, T., Brown, M., Knappett, J., Brennan, A., Augarde, C., Coombs, W., Wang, L., Richards, D., Blake, A., & Ball, J. (2018, June). A modified CPT based installation torque prediction for large screw piles in sand. Presented at Cone Penetration Testing 2018, Delft, Netherlands

Screw piles have been suggested as an alternative foundation solution to straight-shafted piles for jacket supported offshore wind turbines in deep water. The significant environmental loads in the marine environment will require substantially larger... Read More about A modified CPT based installation torque prediction for large screw piles in sand.

On the use of advanced material point methods for problems involving large rotational deformation (2018)
Presentation / Conference Contribution
Wang, L., Coombs, W., & Augarde, C. (2018, June). On the use of advanced material point methods for problems involving large rotational deformation. Paper presented at 6th European Conference on Computational Mechanics and 7th European Conference on Computational Fluid Dynamics, Glasgow, UK

The Material Point Method (MPM) is a quasi Eulerian-Lagrangian approach to solve solid mechanics problems involving large deformations. The standard MPM [1] discretises the physical domain using material points which are advected through a standard f...

Modelling peeling- and pressure-driven propagation of arterial dissection (2017)
Journal Article
Wang, L., Hill, N. A., Roper, S. M., & Luo, X. (2018). Modelling peeling- and pressure-driven propagation of arterial dissection. Journal of Engineering Mathematics, 109(1), 227-238. https://doi.org/10.1007/s10665-017-9948-0

An arterial dissection is a longitudinal tear in the vessel wall, which can create a false lumen for blood flow and may propagate quickly, leading to death. We employ a computational model for a dissection using the extended finite element method wit... Read More about Modelling peeling- and pressure-driven propagation of arterial dissection.

CPT-based design procedure for installation torque prediction for screw piles installed in sand (2017)
Presentation / Conference Contribution
Al-Baghdadi, T., Brown, M., Davidson, C., Knappett, J., Brennan, A., Wang, L., Coombs, W., Augarde, C., Richards, D., & Blake, A. (2017, September). CPT-based design procedure for installation torque prediction for screw piles installed in sand. Presented at 8th International Conference on Offshore Site Investigation & Geotechnics (SUT OSIG), London

Screw piles (helical piles) have been used widely as foundations for onshore projects due to their ability to provide high compressive and tensile resistance as well as reduced noise/vibration during installation. These types of piles have been propo... Read More about CPT-based design procedure for installation torque prediction for screw piles installed in sand.

Implicit MPM with second-order convected particle domain interpolation (2017)
Presentation / Conference Contribution
Wang, L., Coombs, W., Augarde, C., & Brown, M. (2017, April). Implicit MPM with second-order convected particle domain interpolation. Presented at 25th Conference on Computational Mechanics UKACM 2017., Birmingham, UK

An implicit material point method (MPM) with the second-order convected particle interpolation (CPDI2) is presented in this paper. In the MPM a body is described by a number of Lagrangian material points, at which state variables are stored and track...

Modelling screwpile installation using the MPM (2017)
Presentation / Conference Contribution
Wang, L., Coombs, W., Augarde, C., Brown, M., Knappett, J., Brennan, A., Richards, D., & Blake, A. Modelling screwpile installation using the MPM. Presented at 1st International Conference on the Material Point Method (MPM 2017), Delft, Netherlands

Screwpiles are, as the name suggests, piled foundations which are screwed into the ground. They provide restraint to both upwards and downward loading directions and are commonly used for light structures subject to overturning or wind loading, such...
