P. Level et al., SOME CONSIDERATIONS ON MODAL REANALYSIS OF NONCONSERVATIVE DYNAMICS SYSTEMS BY THE GENERALIZED RECEPTANCE METHOD, Computers & structures, 57(6), 1995, pp. 1029-1034
A structural modification technique which takes into account the dampi
ng parameter is introduced in this paper. The applications described a
re the extensions of a method based on the Receptance Approach initial
ly developed by Palazzolo. Numerous efforts have been made in order to
take into consideration the dissipative characteristics of the mechan
ical structures. Specific cases of modifications can lead to simplifie
d algorithms and, as a consequence, to outstanding results. The conclu
sions, which have been drawn up, show the important reductions in term
s of computational times but also in terms of memory size, that we can
expect when this method is implemented in practical engineering desig
