 ===2.3 Elemental damage definition===
-Once damage has been evaluated at each element edge, which corresponds to an virtual DE link, the elemental  is calculated as the maximum damage created at any cut plane existing within the tetrahedron (Figure [[#img-1|1]]). On each tetrahedron there are four cut planes that disconnect one node from the other three nodes (Figure [[#img-1|1]]a) ) and three cut planes that disconnect two nodes from the other two nodes (Figure [[#img-1|1]]b) ).

 * DEM discretization.
 * Substepping time integration of the dynamic equations for the DEM and FEM regions.
 In short, the solution strategy starts by evaluating the transient mechanical behaviour of a finite element (FE) mesh of 4-noded tetrahedra that discretize a solid. The mesh connectivities emulates the discrete element (DE) links were damage is evaluated. The mechanism to transfer an element damage to the DE links is defined by the different cutting planes for each tetrahedron. In this way the element stiffness, affected by the damage, can be defined in a standard form and a new iteration can be made.

 ==Abstract==
-This paper extends to three dimensions (3D) the computational technique developed by the authors in 2D for predicting the onset and evolution of fracture in a finite element mesh in a simple manner based on combining the finite element method (FEM) and the discrete element method (DEM) approach Zarate2D. Once a crack is detected at an element edge, discrete elements are generated at the adjacent element vertexes and a simple DEM mechanism is considered in order to follow the evolution of the crack. The combination of the DEM with simple 4-noded linear tetrahedron elements correctly captures the onset of fracture and its evolution, as shown in several 3D examples of application.
