Publicly-available fatigue test data
Mon, 2009-11-30 11:43 - Mike Graham
Can anyone help point me to publicly-available fatigue or fracture test data? I am interested in obtaining a variety of data for statistical processing. It seems many authors have used the data collected by Virkler and Hillberry which seems to be widely used, but I have not found raw data for their tests so far; is this data available somewhere for me to use? Any help is very appreciated.

Not much information.
I'm somewhat disappointed with my literature search so far. All authors seem to be using the same two datasets, Virkler's and the data of Yang and Manning, both of which seem to be great but somewhat limited. If I can't find the data in a raw enough format I can try to contact Dr Yang, but I do not know where to try to get the Virkler data now that Hillberry has retired. Are these really the only two datasets for fatigue/fracture suitable for statistical analysis out there?
For the record
In case anyone else has a similar issue, I managed to find the raw data collected by Yang et al. The report with the data is available at http://www.dtic.mil/srch/doc?collection=t3&id=ADA173635 and the others in its series are also available at that website.
Free data
Dear Mike,
Well, according to the data sets you refer to, I assume you are interested mostly in crack growth data and models. Anyhow, you've asked for general fatigue material properties, so maybe the link to the free material database I am building can help you a bit. You can find it on http://www.pragtic.com/vmat.php. It is a set of material properties record (with no relation to crack growth, sorry, I am interested in the initiation period) with described links to the original papers. Unfortunately, I cannot provide you any simple table that you could quickly transfer, because I have not programmed something like that yet. If you get interested, we can try to export the data to csv format, but it will cause you a headache, because of the need to link the information between the set of several databases, in which the information is saved. But let me know, if you are interested.
On the other hand, I want to inform you that any registered user can add new data to this database and I would be quite happy if anybody else starts to help me. I think it is not a bad public service
.

Hi All, Could you
Hi All,
Could you please tell me how I can make communication between Matlab and Nastran? Actually I want to send some force data from Simulink to a deformable object in Nastran and then I will read the deformation of the object in Simulink. After that I will recalculate the forces and send it back to Nastran till some desired criteria is made. Can anybody help me to figure out this? Could you please pass it to me if you have any source code?
Thanks in advance

fatigue data
I work with some of my collected fatigue time series (strain loadings) that were measured on a real car component while travelling over various road surfaces in Malaysia.
In addition, www.fatigue.org can give you indication of some SAE data sets.
