RE: Abaqus license error when submitting job with PolyUMod material model calibrated in MCalibration and erroneous import of Yeoh-BB python file

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...

RE: zero transverse shear stiffness

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...

RE: PolyUMod Error: At least 17 material parameters are needed

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

RE: PolyUMod Error: At least 17 material parameters are needed

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...

RE: Does PolyUMod support beam element in dyna?

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

RE: User-Material Model License Error: Could not check out 'polyumod-abaqus' license

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

RE: Contents of the Experimental Data file

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...

RE: Use of shear storage and shear loss modulus in MCalibration

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

RE: Deviation between material model and simulation output

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 ...

RE: Measuring damping using Abaqus and viscoelastic material

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...

RE: Measuring damping using Abaqus and viscoelastic material

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...

RE: How can I add viscoelastic properties in ANSYS Mechanical?

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...
