Presentation / Conference Contribution
Robinson, S., Brown, M., Brennan, A., Cortis, M., Augarde, C., & Coombs, W. (2016). Improving seabed cable plough performance for offshore renewable energy. In C. Guedes Soares, (Ed.), Progress in renewable energies offshore : proceedings of the 2nd International Conference on Renewable Energies Offshore (RENEW2016), Lisbon, Portugal, 24-26 October 2016 (1-7). https://doi.org/10.1201/9781315229256

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.

Parallel computations in nonlinear solid mechanics using adaptive finite element and meshless methods (2016)
Journal Article
Ullah, Z., Coombs, W., & Augarde, C. (2016). Parallel computations in nonlinear solid mechanics using adaptive finite element and meshless methods. Engineering Computations, 33(4), 1161-1191. https://doi.org/10.1108/ec-06-2015-0166

Purpose A variety of meshless methods have been developed in the last twenty years with an intention to solve practical engineering problems, but are limited to small academic problems due to associated high computational cost as compared to the stan...

An Adaptive Cracking Particle Method for 2D Crack Propagation (2016)
Journal Article
Ai, W., & Augarde, C. (2016). An Adaptive Cracking Particle Method for 2D Crack Propagation. International Journal for Numerical Methods in Engineering, 108(13), 1626-1648. https://doi.org/10.1002/nme.5269

Computational modelling of fracture has been attempted in the past with a range of numerical approaches including finite element, extended finite element and meshless methods. The cracking particle method (CPM) of Rabczuk is a pragmatic alternative t... Read More about An Adaptive Cracking Particle Method for 2D Crack Propagation.

Branched crack modelling with the Cracking Particle Method (2016)
Presentation / Conference Contribution
Ai, W., Augarde, C., & Trevelyan, J. (2016). Branched crack modelling with the Cracking Particle Method. In Proceedings of the 24th UK Conference of the Association for Computational Mechanics in Engineering, 31 March - 01 April 2016, Cardiff University, Cardiff (125-128)

Multiple crack simulation is of great importance in failure analysis since fracture in brittle materials in practice usually comprises multiple cracks. Traditional numerical methods like the extended finite element and the element free Galerkin metho... Read More about Branched crack modelling with the Cracking Particle Method.

Implicit essential boundaries in the Material Point Method (2016)
Presentation / Conference Contribution
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.

Gradient elasticity with the material point method (2016)
Presentation / Conference Contribution
Charlton, T., Coombs, W., & Augarde, C. (2016). Gradient elasticity with 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 (112-115)

The Material Point Method (MPM) is a method that allows solid mechanics problems with large deformation and non-linearity to be modelled using particles at which state variables are stored and tracked. Calculations are then carried out on a regular b... Read More about Gradient elasticity with the material point method.

Energy dissipation in granular material under 1D compression (2016)
Presentation / Conference Contribution
Mukwiri, R., Ghaffari Motlagh, Y., Coombs, W., & Augarde, C. (2016). Energy dissipation in granular material under 1D compression. In Proceedings of the 24th UK Conference of the Association for Computational Mechanics in Engineering, 31 March - 01 April 2016, Cardiff University, Cardiff (231-234)

In recent years it has been shown that the micro-mechanics of one-dimensional normal compression of sands can be modelled in three-dimensions within the discrete element method [7]. The compression is displacement driven such that the top platen of t... Read More about Energy dissipation in granular material under 1D compression.

Temporary propping at Crossrail Paddington Station (2016)
