fatigue crack tools
(OP)
Could anyone tell me where can i find the latest information on analysis of crack propagation for composites? From my understanding, we still over design the composite components in aircraft due to not have complete confidence in the analysis tools for crack growth in composite material. Therefore, we prevent the crack growth by preventing the initiation of cracks with a bulk composite design.
Any help and direction will be welcomed.
Thanks

RE: fatigue crack tools
What specific type of structure?
What material system?
What are you specifically trying to invesigate?
Composite aircraft structure is typically designed for "no damage growth" because there are currently no practical NDI methods for detecting and monitoring growth of cracks/delaminations.
There are lots and lots of papers on "cracks" in composites. Try searching for NASA/Langley documents at http://ntrs.nasa.gov/search.jsp or a general literature search thru your library.
