Abstract

The Discrete Element Method (DEM) is a numerical technique used to analyze the motion of discrete particles. DEM is mostly used to analyze the behavior of granular materials such as sand, gravel, powders, etc. The method can also be combined with the Beam Bound Model (BBM), which allow the method to be used for continual problems simulation. However, method is overshadowed in this field by the Finite Element Method. Its primary application is found in problems requiring consideration of both continuum and discrete properties, such as crack propagation, especially in the case of dynamic behaviour. The problem with DEM is its high computational cost, but by using properties specific to the crack propagation problem, efficient methods for solving differential equations can be used. This paper focuses on the efficiency of using the implicit Newmark-beta method to analyze crack propagation in concrete members.
