Feature Request: Nonlinear Composite Properties & Simulate Internal Pressure #286
Comments
Hi @SoundsSerious, sounds like you have some interesting engineering challenges to solve! While both of these ideas are very intriguing, they are outside the scope of

Thanks for the thoughtful response, I think i understand the problem you're describing related to the simplified 2d analysis but I'd need to dig into the code / solver to really understand. I am checking out concrete-properties and this does indeed look very interesting. I hadn't checked it out prior since, well I'm not using concrete, but I think I could potentially model carbon fibre by overlapping sections of epoxy and non linear CF materials and using mass-weighted material properties to adjust for effective volume. Do you think this could work? From example 8.2 in https://robbievanleeuwen.github.io/concrete-properties/notebooks/composite_section.html
I wonder if the functionality between |
Unfortunately I have zero experience in working with carbon fibre so can't really comment on a design methodology.
I'm sure a very similar approach could be used to create a potential In terms of plug-ability, I think the best approach would be using the pre-processor from |
Thanks again for making such an excellent & useful library. Section properties and PyNite are opening up an interesting avenue for the optimization of structures for me.
A couple of features/use cases that would help answer some edge case problems with composites.
Internal Pressure: taking advantage of
Shapely.Polygon.holes
property would it be possible to apply an internal pressure to a section? This would help answer questions about how internal pressure affects/improves strenght for nonlinear materials like CFRP.Nonlinear Tension/Compression materials: This is a pretty well understood problem but it would be great to have the ability to spec a material with different compression/tension properties.
My solution to this at present is to use different tension/compression members in
PyNite
to model this and then handle the load cases separately, however, there are a lot of reasons this is not ideal as it increases the size of the problem significantly by 2-3x if I'm using a composite wrapped isotropic beam.Anyways keep up the great work and hopefully I can find something to contribute to :)
