Project description
A generalized three-dimensional discrete element method with grains cracking
Introduction:
Granular materials are made of discrete particles, when these discrete particles are subjected to stress due to contact forces among them, these particles can be broken. In consecuense to simulate a real system this interaction must be considered to capture the real physics of the system. For this reason we introduce «A generalized three-dimensional discrete element method with grains cracking», that is a generalization of the 3D Level Set DEM with the particularity that the computational particles can be broken following plasticity criteria.

Characteristics:
- Particles are avatar grains obtained from 3D images extracted by X-ray computed tomography (3DXRCT) from a real granular material.
- Particles can be broken when they are subjected to stress, following plasticity criteria.
- The ability to predict plasticity phenomena like Hysteresis.
Benefits:
The ability to capture the physics of a real granular material
