For brittle materials without joints, numerical studies have been implemented by a number of researchers using various numerical codes and models to simulate the processes of fracturing and fragmentation under blasting [7-19].
For each material, we design one sub-grid, thus, for the model shown in Fig. 1, there are two sub-grids for the materials of rock and TNT, and each sub-grid is discretized into a set of rectangular elements.

The conditions of outdoor damage process on materials can be reproduced in a controlled environment at laboratory level.
It is possible to notice a loss of mass after 30 day of exposure and then the materials seems to be stable.
Some of the most easily observed changes are partial strength loss and loss in material density over time (Mass per unit area).
