Abstract : The velocities of elastic waves through the cubic crystal along different orientations are theoretically, calculated using stress-strain relationship in tensor form and secular determinant. These velocities are determined in terms of three elastic constants C_11,C_(12 )&C_44 of cubic crystal. Three values of wave velocities are obtained:one value corresponds to longitudinal velocity and other two identical values corresponds to transverse velocities.The wave velocities along different orientations can be measured experimentally. Using these velocity values, elastic constants for cubic crystal can be obtained.
