with multiple delaminations by considering viscoelasticity as material damping
is studied in the study. A semi-analytical finite element method is utilized
to model guided wave propagation in composite laminates and the viscoelasticity
is modeled by using complex stiffness matrix. Expression of S-parameter is introduced
to describe the sensitivity of guided wave interaction with multiple delaminations
by considering attenuation of amplitude along the propagation direction and
sensitivities of first several mode are illustrated. The results could provide
useful information for the selecting of more effective guided wave modes for
damage detection in composite laminates.]]>Auld, B.A.,1990Bartoli, I., A. Marzani, F. Lanza di Scalea and E. Viola,2006295685707Castaings, M. and B. Hosten,200311326222634Dong, S.B. and R.B.
