An elastic wave is composed of compressional (longitudinal) waves and shear (transverse) waves which have different wave velocities in solids.
The acoustic field presents complex interference patterns which means its phenomena and properties are difficult to reveal.
Fortunately, the energy method is more accurate than the potential function approach in describing the physical properties of the acoustic field.
However, the polarization state of particle vibration excited by an elastic wave is spatially periodic in the wave propagation direction.
Therefore, the energy propagation direction is not consistent with the wave propagation direction using commonly used energy method.
According to the polarization state of particle vibration, a time-space averaging method based on the spatial periodicity of energy flux in the solid is proposed.
The method could eliminate the influence of the interference due to local energy exchange and retain the trend of energy propagation.
Several conclusions are illustrated through the analysis of the scattering energy properties of a steel shell in sandy sediment.
Sandy sediment can not be regarded as a fluid nor a general solid.
Scattering energy excited by an incident shear wave mainly concentrates in the vicinity of the directions of backscattering and forward scattering.
Especially, at low frequency, it plays an important role in the total scattering energy excited by an incident compressional and shear wave.
