Abstract

The discrete element method (DEM) is a numerical method based on the motion and contacts of individual elements. It is mainly used in particle mechanics, because its possibilities of use for continuous problems are overshadowed by other methods, such as the finite element method (FEM). However, its application can be found, for example, in the problem of the size and propagation of cracks in concrete and reinforced concrete structures. These problems combine problems of continuous and particulate behavior, which causes problems in the calculations and optimization of commonly used FEM due to frequent changes in the mesh or the need for parameters that are difficult to detect in common practice. By using DEM, these problems are eliminated, but there is a need to properly define the properties of the solid bonded contacts, which are not found in the conventional DEM. This can be achieved using a variety of methods, this paper is focused on method that insert beams element between each particles called beam bound model.
