  • Online:2015-10-25 Published:2015-10-20

Abstract: Based on the longitudinal wave in a bar, it is shown that the kinetic and potential energy density may have different instantaneous values when the initial stress is presented in the medium.

Key words: simple harmonic wave, elastic potential energy, Young' s modulus
