A new computational method of effective elastic constants of the second and third order of multi-component
geologic media is considered. Effects of the structure of crack-pore space on effective elastic Lame
constants of the third order of model of quartz sandstone are investigated. With water saturation of
micro-cracks of the format
=0,0001 non-linear effective elastic constants v1*,
v2* change by
several orders, non-linear effective elastic constant v3* changes considerably less.
