Conference Proceeding
Ghaffari Motlagh, Y., & Coombs, W. (2016). A high-order 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 (352-355)

The material point method (MPM) is a version of the particle-in-cell (PIC) which has substantial advantages over pure Lagrangian or Eulerian methods in numerical simulations of problems involving large deformations. Using MPM helps to avoid mesh dist... Read More about A high-order material point method.

Energy dissipation in granular material under 1D compression (2016)
Conference Proceeding
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.
