Damage Tolerance R-Curves

Damage Tolerance R-Curves

Any good open source material which provides practical information on implementation of R-Curves for DT Design of Aerospace structures?

RE: Damage Tolerance R-Curves


Not sure if this is what you are looking for (maybe you've already looked here) but there is some good info on using R-curves in the following:

Farahmand - Fatigue and Fracture of High Risk Parts - Section 3.4.3
Broek - The Practical Use of Fracture Mechanics - Section 10.6
Broek - Elementary Engineering Fracture Mechanics - Section 8.3
Damage Tolerance Assessment Handbook Volume 1 - Section 2.4.1

I might also go to the NASA Technical Reports Server and search for "r-curve". It may be beneficial to look at the list of references in any reports that come up. If you can track those down they may help you.

RE: Damage Tolerance R-Curves

I have a copy of SigmaK's FDT book. It contains some basic info along with a practical example of using R-curve for a skin panel. I got some idea about practical part of it.

I have gone through 2 of 4 references you have mentioned and Broek is good for understanding the physics part of it. Thanks for your post.
