Question

Hi everyone,

I'm a Master's student working on mesoscale modeling of woven textiles using 3D voxel meshes. I am looking to implement an anisotropic continuum damage model (Transversely Isotropic or fully Orthotropic) to capture stiffness degradation based on criteria like Hashin or Tsai-Wu.

Before I write a custom material class from scratch, I wanted to ask the community:

Has anyone already created and published an open-source MOOSE App or custom material class for 3D orthotropic composite damage?

Any pointers to existing repositories or examples would be hugely appreciated. Thank you!

do you know?

Not that I know of. This would be better done using FFT rather than FEM. If you want to stay within the moose ecosystem, @dschwen has an app called Marlin for that. NEML2 has transversely isotropic and orthotopic elasticity models, and you can extend it to incorporate your own damage model. This sounds like a doable and fun master's project.

If you want to stick to FEM, I think Blackbear has some damage models that you can follow.

Thanks for these suggestions, I will look into each of them. Thank you!
