Hmm. Are you using a student version of Abaqus? I believe the student version of Abaqus does not allow for user-material subroutines (like the PolyU...

Yes, there is a simple solution. You just need to tell Abaqus what the transverse shear stiffness to use. The Abaqus command is: *Transverse Shear S...

Hello FelixK, Can you also attach or email your mcal-file? /Jorgen

Good to hear that you were able to solve the problem. /Jorgen

One more thing. You can also ask for technical support by directly emailing to: support at polymerfem dot com. /Jorgen

All you need to do is to copy the k-file commands generated by MCalibration right into the LS-DYNA k-file that you want to analyze. Note that all Poly...

It should support all 2D and 3D element types. We have not yet added support for beam elements due to low demand. /Jorgen

lsdyna i=file.k jobid=tmp ncpu=4

The way to specify the number of CPUs to use is different for each FE solver. Just read your FE Solver Manual to find out how. /Jorgen

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 MCalibr...

If your DMA data is in shear then you should specify shear as the loading mode in the Load Case dialog in MCalibration. Here's an image. /Jorgen

Hello Sebastian, That sounds strange. What you tried should just have worked! There is no need to run tests at multiple rates if you did the "smart ...

I would create a single load-unload cycle with the appropriate strain rate (based on your eigenfrequency or known loading rate), and then simulate the...

Your approach should work. I recommend that you make sure your FE mesh is refined enough, and that your material model dissipates energy at the strain...

Hello Ioana, I don't quite follow what you tried. I agree, though, that you should have seen viscoelastic relaxation in your prediction if the p...
