Abstract
A recently reported new technique renders speckle interferometry appli cable for measuring high local displacement gradients. This paper repo rts how the technique is used to detect and quantify damage in fatigue d carbon fibre-reinforced plastic laminates via its effect on surface displacements. Moreover, the measured displacement fields are used to verify a finite element damage model. The accuracy of the delamination measurement is confirmed by ultrasonic results.
