Hello Kristine, That sounds like an interesting project! What is the max strain and strain rate that you expect to see? DMA is a reasonable start, b...

I'm happy to help. First question: does your k-file work if you run it from a command line: "C:\Program Files\PolymerFEM\PolyUMod\PolyUMod_LSDYNA\ls...

I just created an article and a YouTube movie that shows how you can use MCalibration to convert your storage and loss modulus data into a material mo...

Here are a few comments: 1. Yes. That sounds right to me. 2. I'm not sure about that. You will have to study the documentation for the DEFLUX subr...

1. Yes, you can use a linear elastic material model (Prony series) at large deformations. 2. I would try full integration (not reduced integration)....

Good question. You can request a free trial license to my implementation of the TNM or BB models on the PolymerFEM.com homepage. If you are a student,...

It looks like traditional hourglassing but since you see the same problem with C3D8 elements, that cannot be the reason for the behavior. Another ex...

Note the same command also works on RedHat 7 and CentOS 7.

Remember that MCalibration can very quickly and easily calibrate the ANSYS BB-model. -Jorgen
