When an acoustic plane wave is incident on a elastic plate, various wave
types are excited in the plate for different angles of incidence. The present
study determines the structural intensity as a function of incident angle at
different depths along the cross section. It is found that for near normal
incidence the direction of the intensity parallel to the plane of the plate is
opposite the intensity in the fluid and for other angles of incidence.
