Rotated slip traces

[eugenianietov]

Hi all!!

I'm using DefDAP for analyzing slip traces in my Ti sample. I know in advance that all my traces correspond to prismatic slip. However, when I read my EBSD file with DefDAP, all the predicted traces were rotated -90 degrees, so I cannot find any match. Any idea of what can be happening or how to fix it? I'm using the develop branch of the code!

Thanks a lot in advance!

Hi Eugenia,

Is the loading direction defined correctly for your test? I think the default on the introductory notebook is (1,0,0), I.e loading in the x direction. If you loading is along y, this would need to be (0,1,0).

Kind regards

Dave

Hi Dave,

My loading direction is the x-axis, so I didn´t change it. In fact, the Schmid factors for every slip system are correct, but the traces are not, they are all rotated. Moreover, the DIC and the EBSD match spatially so I didn't apply any rotation.

Thanks a lot!
