I am very much thankful to you Mr.Chris for your valuable codes which is helping me a lot. Since I am a beginner I am unable to understand the logic behind the codes you have written but analyzing images here just by replacing & renaming it. Your guide was so useful & it made my process easy and comfortable.
I have a question for you. When I visualize the analysed data I am unable to see the results for Y direction displacement in strain plots. I have also seen by rotate X,Y option but only the image gets flipped 90 degrees. Is it y displacement..??.. If it is why the title is given there as Raw displacement in X direction..
One more query is How to get the E(xy) strain component..?
I would be very happy if I get a receptive response from you since I am doing my INTERNSHIP now & Your reply can make huge changes here.
I am very much thankful to you once again.
After running 3D mesh plot of displacement, and deleting markers I then use the 'save validx and valid y' button in the menu. I can save the .dat files, however I get the same error every time I try to open them:
Undefined function 'sum' for input arguments of type 'cell'.
Error in mean (line 30)
y = sum(x,dim)/size(x,dim);
Error in displacement (line 52)
I don't get this error with the original validx and y files. But then I need to re-delete badly tracked markers. Has anyone encountered this?
Thanks for the code
hello, thanks for the code.,
it would be of great help,if you could send the edited copy of the same 'to save the values of displacement vs position'
to following address : firstname.lastname@example.org
hello, really appreciate for your work. I'm a student in Sheffield University.
i'm using your code for deformation measurement. I met some difficulties of extracting numerical data from the DIC result figure. could you help out? really thanks.
Over the last two years, I have been using and modifying this code, and I have recently posted my modified version on to Matlab's File Exchange, under File ID #43073. Key improvements that my modified code contains are as follows:
-- Displacements are calculated for each image.
-- Strains are calculated by interpolating displacements using finite element shape functions.
-- The computation time has been greatly reduced through several means, including an option to run the code in parallel mode on multiple cores when processing large number of images.
-- The entire code is wrapped in graphical user interfaces (GUIs) in order to make using the code easier and more straight forward.
If you have been using this DIC code by Christoph Eberl, then you may consider looking at the improvements I made.
Thanks again to Christoph and his colleagues for making a great code, which formed the base of my code.
