異方性媒質中の平面波速度と球面波速度およびエネルギー伝播

抄録

Conception of the “wave surface” related to spherical wave and of the “velocity surface” related to plane wave in anisotropic media is mentioned. We measured experimentally the wave surface with Sanbagawa green schist (No. 904). Further, we measured elastic constants of this Sanbagawa green schist, and the wave surfaces obtained from experiments and calculation were consistent. We measured the direction of energy flow with green schist. This direction was closely related to the wave surface.
