A quantitative discrete element model to investigate sub-surface damage due to surface polishing
TypeCommunications avec actes
This work is a continuation of a previous study that investigated sub-surface damage in silica glass due to surface polishing. In this previous study, discrete element models have shown qualitatively good agreement with experiments. The presented work propose a model allowing quantitative results by focusing on the continuous part of the problem. Special attemption was given to the discrete element model of silica glass considered as perfectly isotropic, elastic and brittle. To validate this approach, numerical results are compared to experimental data from literature.

Using the discrete element method to simulate brittle fracture in the indentation of a silica glass with a blunt indenter ANDRÉ, Damien; JEBAHI, Mohamed; IORDANOFF, Ivan; CHARLES, Jean-Luc; NÉAUPORT, Jérôme (Elsevier, 2013)The mechanical behavior of materials is usually simulated by a continuous mechanics approach. However, noncontinuous phenomena such as multi-fracturing cannot be accurately simulated using a continuous description. The ...
