Hello Prost,
Actually as you suggested, for the S-N data analysis I have already used the fatigue life model according to the MIL-HDBK-5 procedure and derive the curve fitting equation using Microcal Origin software. The equation can be typed and you can get the parameters A, B, ... as you...
Dear All,
I would like to curve fit fatigue S-N and crack growth da/dN-dK data. Can anybody suggest me a regression analysis and curve fitting software suitable for this? Thanks.

CM400T,
I do not agree with you CM. The discussion worth every bit of it, at least for myself, and if I may see myself as being part of the FE community. After reading all the given comments the message is simple: share of information and a reflection and a review of our stand point. And it is...
bohrer,
take a look into thread31-121526..

Basically I have the same doubt as you are.
To answer your question, the best thing is for you to perform coupon test with different interference level. But you have to be carefull, which type...

MNLiaison, as you know generally the fatigue performance of a structural joint, for instance in a sheet metal lap joint, will be depending on the :
1. Number of rivet rows
2. Rivet diameter, and
3. Rivet type
Regarding the rivet types, you need to compare qualitatively the hole filling...
ARDTL,
Do you have a limitation how deep you can scarf a component made of CC ? And do you need to implement a dedicated inspection program or can it be just fire and forget?

Monolithic Alu, just the usual Aluminum sheet or plate, not laminates, ARALL, or Glare.
If I understand correctly, FAA required a full scale composite fuselage test article for the crash test. Cannot it be a smaller scale or only a few frame bays of fuselage structure only? Is there any...
Dear All,
So Boeing has carried out their composite fuselage 787 crash test...
Is it a new requirement only for composite fuselage or also for monolithic Aluminium ?
