[So...] Posted September 16 Share Posted September 16 Dear community, does someone know how I can calculate the strain of each single facet and export this? Thank you! Sophie Link to comment Share on other sites More sharing options...
[Mo...] Posted September 16 Share Posted September 16 Hello Sophie, in order to calculate the srain you need to create the surface component then you select the created surface component in Explorer by click on it, and you go to inspection in menu ->Check dimensions->Check Epsilon as you see in the attached image 2- you select in the explorer the inspection lets say Epsilon x then in the menu file-> export->stage data->CSV: As you see in the attached image Best regards Mohamed Link to comment Share on other sites More sharing options...
[Th...] Posted September 20 Share Posted September 20 Hi Sophie, if I get you right, you want the strain in one facet calculated from a tensor regarding the four corners of a facet?! There is currently no possibility to do this. The strain is always calculated from a neighborhood of points (each point is depending on a facet). Then the procedure is as Mohamed described neatly. But we heard the wish and I will count up the number of people who asked for this feature. Thank you for your feedback! Best, Thorsten Link to comment Share on other sites More sharing options...
[So...] Posted November 1 Author Share Posted November 1 Dear Mohamed, dear Thorsten, thank you very much for the replies. I think the workflow described by Mohamed works for me. I was just wondering what exactly is described by x and y (coordinates?)? As there are decimal I reckon its not pixel coordinates which I would expect. Do you know this by any chance? All the best, Sophie Link to comment Share on other sites More sharing options...
[Th...] Posted November 4 Share Posted November 4 Dear Sophie, the strains are given in local coordinate systems in 3D! Pixel strains are not given! Also if you have a 2D measurement strains are represented in 3D (with z=0). The local z-axis are facing normal to the surface and the x- and y-acis are (more or less) projections of the global coordinate system to the local one. You can also inspect the surface for its strain directions: Inspection => Check Dimensions => Strains => Direction epsilon... You will get an indicator on the surfaces. Hope this helps.

[So...] Posted November 12 Author Share Posted November 12 Dear Thorsten, thank you for the explanation. What I don't get is in which unit are the locations given? The strain is clear. But for each facet an x and y coordinate is in the csv-sheet, some numbers like 19.3411 and 24.5663, which cannot be pixels. This is also relevant for the displacement. I can check for the displacement in the same way as for the strain, but the units are not clear for me. In the sheet it says 'mm', but this is not possible as I never correlate pixel size with a length. Is there something I miss? Thank you for your patience and advice Sophie Link to comment Share on other sites More sharing options...
[Th...] Posted November 13 Share Posted November 13 Hi Sophie, could you please post a screenshot of your project and the corresponding exported csv-file?! Is it a 2D-measurement? 3D with ARAMIS?! All coordinates are given in your global 3D coordinate system. Meaning if you have a 2D measurement it is quite normal to have something like 19.3 ; 24.6 ; 0 19.1 ; 25.7 ; 0 ... and everything in [mm]. You will always have some default relation, if you didn't actually choose it. You can find the command at "Operations -Measurements - Define 2D Scale" (SW2023, formerly it was at the creation parameters of the measurement list) or directly in your maintoolbar of the inspection workspace.
