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.

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.

Discrete-element-method model for frictional fibers
Physical Review E, 2023 We present a Discrete Element Method algorithm for the simulation of elastic fibers in frictional contacts. The fibers are modeled as chains of cylindrical segments connected to each other by springs taking into account elongation, bending and torsion forces.

The soft discrete element method
Granular Matter, 2021 In order to accelerate simulations of assemblies of highly deformable grains, a novel numerical approach, called Soft Discrete Element Method (SDEM) is presented. It consists in extending the classical DEM by introducing the deformability of the grains in a simplified way.

Boundary element method based on preliminary discretization [PDF]
Mathematical Models and Computer Simulations, 2014 The final publication is available at Springer via http://dx.doi.org/10.1134/S2070048214020082 A new numerical method for solving wave diffraction problems is given. The method is based on the concept of boundary elements; i.e., the unknown values are the field values on the surface of the scatterer. An analog of a boundary element method rather than a

Water retention in discrete element method [PDF]
AIP Conference Proceedings, 2013 We describe water movement and retention using the discrete element method in view of future modelling of partially saturated granular materials. By defining the water potential in terms of capillary bridges at low saturation, and in terms of pressure of entrapped air at high saturation, we investigate the hysteresis of water retention in granular ...

Rod-Bonded Discrete Element Method
Graphical ModelsThe Bonded Discrete Element Method (BDEM) has raised interests in the graphics community in recent years because of its good performance in fracture simulations. However, current explicit BDEM usually needs to work under very small time steps to avoid numerical instability.
