The interaction of Rayleigh waves with delaminations in composite laminates
, 2014 In the present work, the interaction of Rayleigh waves with a delamination in a fiber reinforced composite plate was analyzed. Rayleigh waves, upon interactingwith delamination mode, convert into Lamb waves in the delamination zone.
