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)
Conference Proceeding
Robinson, S., Brown, M., Brennan, A., Cortis, M., Augarde, C., & Coombs, W. (2017). Improvement of seabed cable plough tow force prediction models. In Offshore site investigation and geotechnics : integrated geotechnologies - present and future. Proceedings of the 8th international conference, held 12–14 September 2017 at the Royal Geographical Society, London (914-921)

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
Cortis, M., Coombs, W., Augarde, C., Brown, M., Brennan, A., & Robinson, S. (2018). Imposition of essential boundary conditions in the material point method. International Journal for Numerical Methods in Engineering, 113(1), 130-152. https://doi.org/10.1002/nme.5606

There is increasing interest in the Material Point Method (MPM) as a means of modelling solid mechanics problems in which very large deformations occur, e.g. in the study of landslides and metal forming, however some aspects vital to wider use of the...

The modelling of soil-tool interaction using the material point method (2017)
Conference Proceeding
Cortis, M., Coombs, W. M., Augarde, C. E., Robinson, S., Brennan, A., & Brown, M. (2017). The modelling of soil-tool interaction using the material point method. In A. Faramarzi, & S. Dirar (Eds.), Proceedings of the 25th Conference on Computational Mechanics (UKACM 2017) : 11th – 13th April 2017, School of Engineering, University of Birmingham, Birmingham, UK (211-214)

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...

Ploughing of the seabed is needed for the installation of cables and pipelines and is an area of construction likely to increase given plans in the UK and elsewhere for offshore marine energy (wind and tidal). Seabed ploughing is an expensive and som... Read More about Modelling seabed ploughing using the material point method.

Seabed ploughing plays an important part in providing protection to subsea cables that connect offshore renewables, and the process represents a significant portion of the overall installation cost. Current models for predicting the required tow forc... Read More about Improving seabed cable plough performance for offshore renewable energy.

Implicit essential boundaries in the Material Point Method (2016)
Conference Proceeding
Cortis, M., Coombs, W., & Augarde, C. (2016). Implicit essential boundaries in the Material Point Method. In Proceedings of the 24th UK Conference of the Association for Computational Mechanics in Engineering, 31 March - 01 April 2016, Cardiff University, Cardiff (116-119)

The Material Point Method (MPM) is a numerical boundary value problem (BVP) solver developed from particle- in-cell (PIC) methods that discretises the continuum into a set of material points. Information at these material points is mapped to a backgr... Read More about Implicit essential boundaries in the Material Point Method.
