Abstract

Dynamic crack propagation in an unidirectional Carbon/Epoxy composite was studied. It was shown that the friction coefficient along the crack surface plays an important role by smearing the discontinuous field that develops behind the crack tip and by reducing crack speed in the intersonic regime. The results showed that the contour integral computed at near field contours are path independent and can serve as a parameter for characterizing intersonic crack propagation.
