Feb 10, 2012 — It is breaking taps left and right. We are cutting 6-32 threads in 6061 T6 usually using straight flute spiral point taps.

N2 - Delamination, that is, crack growth between different plies, is a common failure mode in laminated composites. Analysis, testing, and designing against delamination crack growth is discussed in the present chapter. In comparison with crack growth in isotropic metals, delamination of composites is complicated by elastic orthotropy, mixed mode interface crack growth, and large-scale bridging. This sets special focus on the use of dedicated fracture mechanics testing specimens and theory to characterize delamination. J integral specimens are preferred for the determination of bridging laws (traction-separation laws) to describe large-scale bridging. Furthermore, micromechanical models describing toughening due to crack bridging are briefly reviewed.
