Abstract
The response of soda-lime glass subjected to the stress field induced by the static indentation of a spherical indenter is studied using continuum damage mechanics (CDM). An anisotropic damage tensor with linear damage evolution law is chosen to model the cracking damage. An axisymmetric finite element model is generated to simulate the static indentation process. The damage pattern and zone size are predicted for both the loading cycle and the unloading cycle, and the comparison between the predictions and the experimental results reported in the open literature serves as a validation of the CDM model and the modeling procedure.
