A nonlinear plane longitudinal elastic displacement wave is studied theoretically within the framework of the Murnaghan model for a harmonic initial profile. The main novelty is that the evolution of waves is analyzed by the developed approximate method of constraints on the displacement gradient within the framework of two-phase mixture theory. It is shown that the initially excited wave is divided into four modes, all modes are dispersed and distorted, and each mode wave is represented as a superposition of the first and second harmonics. The amplitude of the second harmonic depends on many parameters, including the direct dependence on time. This dependence means that the second harmonic will dominate over time.
