The Energy Current of Elastic Wave |
| |
| Abstract: | In this paper, based on stress work, a general expression about instant caneous energy current density vector of an arbitrary elastic wave is given.Instantaneous energy current density vectors of some common elastic waves are discussed on the values and directions. The problem about the elastic wave's energy transmission has been solved satisfactorily in this paper. |
