Hello! To get a model for Shape memory polymer, I need to load data file obtained after DMA test. But there is a point, in such data file I haven't any values of "mean strain" or "strain amplitude", I have only E' and E''. Could you please explain what should I do in this case? The test was conducted with constant frequency (it means temperature-dependent).
Contents of the Experimental Data file
When you run a DMA test, the test system always uses a mean strain and a strain amplitude during the test. I recommend that you edit your experimental file so that it contains those values. If you don't know what they were, and you cannot find out, then I would add "fake" data for that info.
I am trying to calibrate an Abaqus material model to some test data I have. However, when I run the calibration photo 24 Hour Petrol Station the ofy I receive the error 'The specified path to abaqus is not valid. Please change the abaqus path in the global preferences dialog'. I have ensured that the Abaqus path is the same as that stated in the instructions and so it points to my abaqus.bat file. Does anyone know what might be the solution to this issue? (I am using a trial license of MCalibration, I don't know if this should make any difference?).
Hiii! I must load the data file generated from the DMA test in order to obtain a model for the Shape memory polymer. However, there is one problem: I just have the values E' and E" in this data file, not any mean strain or strain amplitude values. Please tell what I should do in this situation. The experiment was carried out repeatedly (it means temperature-dependent).
In that case you should add a column for mean strain, and one column for the strain amplitude. You can add those columns using Excel or within MCalibration. I recommend that you add a constant value of mean strain of 0 (zero), and constant value of strain amplitude of 0.001. Or you can, of course, use other values if you have more info.
