On Impact Fracture Analysis of Brittle Material Beam using DEM

Abstract

When a static load is applied to a brittle material beam, the beam fractures at the fixed end. However, such a phenomenon does not necessarily happen in the case of dynamic load. In dynamic load the fracture behavior changes with the situation of the stress wave propagation, the material properties and the shape of beam. In this research, an impact fracture behavior of brittle material beam is analyzed using the discrete element method (DEM), and the results are compared with the experiment values. From the results, the impact fracture mechanism of brittle material beam is considered.
