A variational integrator for the Discrete Element Method [PDF]
Journal of Computational Physics, 2022 A novel implicit integration scheme for the Discrete Element Method (DEM) based on the variational integrator approach is presented. The numerical solver provides a fully dynamical description that, notably, reduces to an energy minimisation scheme in the quasi-static limit.

Simulating Fractures With Bonded Discrete Element Method [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2022 Along with motion and deformation, fracture is a fundamental behaviour for solid materials, playing a critical role in physically-based animation. Many simulation methods including both continuum and discrete approaches have been used by the graphics community to animate fractures for various materials.
