Calibration of beam bound model for the discrete element method
Original language description
The discrete element method (DEM) is a numerical method based on the motion andcontacts of individual elements. It is mainly used in particle mechanics, because itspossibilities of use for continuous problems are overshadowed by other methods, suchas 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 reinforcedconcrete structures. These problems combine problems of continuous and particulatebehavior, which causes problems in the calculations and optimization of commonlyused FEM due to frequent changes in the mesh or the need for parameters that aredifficult 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, whichare 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 particlescalled beam bound model (BBM).
