A quantitative discrete element model to investigate sub-surface damage due to surface polishing

摘要

This work is a continuation of a previous study that investigatedsub-surface damage in silica glass due to surface polishing.In this previous study, discrete element models have shownqualitatively good agreement with experiments. The presentedwork propose a model allowing quantitative results by focusingon the continuous part of the problem. Special attemption wasgiven to the discrete element model of silica glass considered asperfectly isotropic, elastic and brittle. To validate this approach,numerical results are compared to experimental data from literature.
