Computer Methods in Applied Mechanics and Engineering, 2004 The paper presents combination of discrete element method (DEM) and finite element method (FEM) for dynamic analysis of geomechanics problems. Combined models can employ spherical (or cylindrical in 2D) rigid elements and finite elements in the ...

Discrete Element Modeling of the Seismic Behavior of Masonry Construction
Buildings, 2019 Discrete element models are a powerful tool for the analysis of masonry, given their ability to represent the discontinuous nature of these structures, and to simulate the most common deformation and failure modes.

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.
