I'm trying to model the deformation of a ribbon of SU8 with a pattern of cuts (kirigami) undergoing a 1D tensile loading. The loading is kept in the xy plane, but the force causes a twisting of material and buckling in the Z direction. Attached is an example photo of it occurring to paper with similar conditions. I cannot recreate what is happening physically within COMSOL
I've attempted this as a thin solid as well as a shell, both ending with the same result of only showing strain and deformation within the xy plane. I have assigned one end as a fixed constraint while attempting edge/boundary loading or prescribed displacement. I have also tried conducting a Linear Buckling study, but it doesn't provide me with the results I need I'm assuming because the loading is tensile and not compression. Attached is the file I'm trying to work with. I'm still new to COMSOL so I may be doing something wrong. Are there any suggestions for what may work or that I'm missing?
