摘要：

The complete set of the room-temperature third-order elastic moduli of CaF2 were determined from the change in the sound velocity under uniaxial compression. The measured values in units of 1011 dyn/cm2 are C111=-124.6, C112=-40.0, C123=-25.4, C144=-12.4, C166=-21.4, and C456=-7.5. The experimentally measured third-order elastic moduli are compared with the theoretically calculated ones, and a good agreement is found. Conclusions pertaining to the lattice-force interactions are presented. © 1969 The American Physical Society.
