Overcoming volumetric locking in material point methods (2018)
Journal Article
Coombs, W., Charlton, T., Cortis, M., & Augarde, C. (2018). Overcoming volumetric locking in material point methods. Computer Methods in Applied Mechanics and Engineering, 333, 1-21. https://doi.org/10.1016/j.cma.2018.01.010

Material point methods suffer from volumetric locking when modelling near incompressible materials due to the combination of a low-order computational mesh and large numbers of material points per element. Large numbers of material points per element... Read More about Overcoming volumetric locking in material point methods.

Improvement of seabed cable plough tow force prediction models (2017)
Presentation / Conference Contribution
Robinson, S., Brown, M., Brennan, A., Cortis, M., Augarde, C., & Coombs, W. (2017, September). Improvement of seabed cable plough tow force prediction models. Presented at 8th International Conference on Offshore Site Investigation & Geotechnics (SUT OSIG), London, England

As the use of offshore renewable energy sources such as wind and wave energy systems expands, they represent an increasing portion of the energy mix. Subsea cables connecting these resources are subject to many hazards, making cable burial using cabl... Read More about Improvement of seabed cable plough tow force prediction models.

Imposition of essential boundary conditions in the material point method (2017)
Journal Article

The modelling of soil-tool interaction using the material point method (2017)
Presentation / Conference Contribution
Cortis, M., Coombs, W. M., Augarde, C. E., Robinson, S., Brennan, A., & Brown, M. (2017, April). The modelling of soil-tool interaction using the material point method. Presented at 25th Conference on Computational Mechanics UKACM 2017., Birmingham, UK

The material point method (MPM) is a numerical tool able to model very large deformations in solid mechanics such as geotechnical problems. To date, soil-tool interaction modelling in the MPM is somewhat difficult, especially when the tool position i...

An implicit implementation of non-ordinary state-based peridynamics (2017)
Presentation / Conference Contribution
Hashim, N., Coombs, W., Hattori, G., & Augarde, C. (2017, April). An implicit implementation of non-ordinary state-based peridynamics. Presented at 25th Conference on Computational Mechanics UKACM 2017., Birmingham, UK

Peridynamics is a non-local continuum theory that was introduced by Silling. Its key advantage is its use of integral equation forms of the underlying physics, as compared to the partial differential equations in, say the finite element method and th...

Energy dissipation in granular materials in triaxial tests (2017)
Presentation / Conference Contribution
Mukwiri, R., Ghaffari Motlagh, Y., Coombs, W., & Augarde, C. (2017, April). Energy dissipation in granular materials in triaxial tests. Presented at 25th Conference on Computational Mechanics UKACM 2017., Birmingham, UK

The triaxial test is used in a laboratory to investigate the behaviour of geotechnical materials (e.g. clays and sands). The difficulty in measuring some properties of granular media such as energy changes throughout the test have motivated the curre...
