GEO-MIX-SELF calculations of the elastic properties of a textured graphite sample at different hydrostatic pressures

A combination of self-consistent and geometric mean algorithms is applied to describe the pressure-dependent anisotropic elastic properties of a textured reactor graphite sample. The experimental sound velocities can reasonably be explained by a system of differently oriented extremely anisotropic flat grains, flat micropores (cracks) and spherical macropores with comparable volume fractions in the porous (∼20%) sample.
