Scattering Sensitivity in Viscoelastic Composite with Multiple Delaminations
Zhang Hong and Deng Qing-Tian

Abstract:
Scattering sensitivity of guided wave in composite laminate 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.
