Analysis of Delamination Growth near Intersecting Ply Cracks Academic Article uri icon

abstract

  • Three-dimensional finite element analysis was used to study cross-ply laminates with a delamination near the intersection of orthogonal ply cracks. Three lami nates were studied: (0/90)s, (90/0)s, and ((0/90)s∞. Mode mix was sensitive to stacking sequence, location along the delamination front, and delamination shape and size. The mode III component was generally the largest component. For loading in the x-direction, there were extremely strong gradients of GIGIIInear the yz-plane, where the delami nation front intersected a ply crack. © 1992, Sage Publications.
