This paper reports the application of a self-consistent integral equation technique to the calculation of the elastic constants of polycrystalline graphite. The self-consistent expressions used in this paper are restricted to spherical grains and pores and neglect correlation among grains and pores.
A calculation is presented of the elastic constant CM of a graphite crystal as a function of temperature up to 2500 K, taking into account the anharmonic contribution and the changes in interlayer interactions due to the large lattice thermal expansion. Parametric variations in the theory show that
