lower than the constants c alculated along a and b consis-
tent with the crystal structure of kaolinite [22].
4. Conclusions
In summary, these calculations have shown that the
computational techniques are a useful tool for investi-
gating clay structures and mechanical properties. Pre-
dicting the mechanical properties of minerals that are
difficult to obtain experimentally because of their small
particle size (typically <2 micrometers).
