Using the discrete element method to simulate brittle fracture in the indentation of a silica glass with a blunt indenter
We propose a novel failure criterion for simulating continuous media within a Discrete Element Model. The calibration of this criterion is described. The criterion is validated by numerical tensile, bending and torsion failure tests. An application on indentation tests is proposed. The results are compared to experimental observations.
