In this paper, we use the method of Fourier analysis to derive the formula of the total energy for the Cauchy problem of the Cauchy–Navier elastodynamics wave equation describing the motion of an isotropic elastic body. The conservation law of the total energy is obtained and consequently, the global uniqueness of the solution to the problem is implied.
