Abstract: A numerical method of integration of Green's functions of strip
element method (SEM) is proposed. The response of ultrasonic
source generated by a transducer on the surface of a multi-ply
composite plate containing a delamination is analyzed by the use
of SEM. The numerical results show that the scanning features of
the ultrasonic waves may be used to identify the delamination
inside the composite plate.
Key words: Strip element method (SEM) Delamination Composite plate
