Crack propagation analysis in radios

Surya Koneti

Hi everyone,

I'm currently working on a project involving crack propagation analysis using Altair Radioss. I'm looking for guidance on how to set up and conduct this type of simulation effectively. Could anyone share a step-by-step approach or point me to any official documentation, tutorials, or example files that could help?

Any insights, references, or shared experiences would be greatly appreciated!

Thank you in advance.

Hi,

Depending on how you want to represent the failure, there are different approaches.
There are failure models that can represent crack along the part with /FAIL/BIQUAD, although it doesn't have specific inputs for crack growth and propagation. Here is an example of that: Integration of non-local regularization into simulations. — Altair Community

And there is a failure model based on crack-growth, /FAIL/ALTER: https://help.altair.com/hwsolvers/rad/topics/solvers/rad/fail_alter_starter_r.htm?zoom_highlight=%2FFAIL%2FALTER

Here you can find an article about that: Windshield 3-point-bendingtest with /FAIL/ALTER — Altair Community

Best regards,
