The precision of damping distribution identification is limited
due to the shape of the weighting function. This limitation can
be potentially surpassed by loosening the constrain of unequivocal
assignment of weights through an application of standing wave
with more than half wavelength. In further studies the shape of
the travelling waves will be optimised in order to assure an identification
of damping distribution with resolution appropriate for
practical applications. Furthermore, experimental validation on
specimens with artificially and impact-caused changed damping
distribution will be addressed.
