摘要
The pressure dependences of the second-order elastic constants C-ij and the velocity of sound in 3C-SiC and 2H-SiC crystals are calculated in the framework of the Keating model. The third-order elastic constants C-ijk for 3C-SiC are determined from the dependences of the second-order elastic constants C-ij on the pressure p. (C) 2004 MAIK "Nauka / Interperiodica".
