Simulating a 3d print over stretched fabric effect

[rhinoyotam3]

Hey guys,
lately, I have been making some experiences and tried to 3d print simple lines over some
stretched lycra fabrics.
I want to create a model that will simulate the bending result (adding reference pictures),
but currently, I am a bit clueless about how to do so.

I realized that in order to simulate a stretched fabric, I should apply forces
by using the ‘edge length’ component over a mesh. I was wondering if there is a way to apply different edge lengths to a single mesh, and by doing so making it bend in a specific manner.

I am adding a very simple grasshopper file, as a starting point.

(hopefully, I will add a better file soon)

thanks!

Simulation of Tensile Textiles and 3d printing

Hello I was wondering if is there any chance to simulate(even unnacurately) the behaviour of a textile of any fabric like lycra to see how it folds after you 3D print over it. [4D printing Programmable Textiles HD] I attached a youtube link for the behaviour of the textile I want to simuate. I am relatively new with kangaroo I read the manual and made several examples to make tensile structures but I dont know if there is any way to simulate that behaviour with kangaroo. The idea …

3D deformation of a 2D frame due to shrinkage

Hello everyone, I would like to get some opinions on how to simulate something in gh that I have been experimenting within physical models. In the attached photos you can see some cork-bioplastic tiles. Initially, cork works as 2d frame to contain bioplastic while it dehydrates. But as bioplastic dehydrates, it shrinks and as a result, deforms the cork frame 3d. From physical experiments, I know that there are so many other parameters apart from frame(humidity, hanging orientation, temperature,…

hey @DanielPiker,
Thank you very much for your answer!
I was looking at the examples, and all of them are bounded by a closed rod.
Is there a way to create that shrinking effect in the middle of a mesh?
my final goal is to be able to create different patterns
such as shown here
(or simulate other patterns)

One way could be to make it all one mesh, and treat the bending parts as shells, and for the rest reduce the rest length by some factor to give tension like this

This would be great for David Shorey to test his amazing 3D prints on textiles beforehand.
