Mora S., Pugno N.M., and Misseroni D. "Programming the energy landscape of 3D-printed Kresling origami via crease geometry and viscosity." Extreme Mechanics Letters (2025): 102314. (DOI: https://doi.org/10.1016/j.eml.2025.102314)

The data supporting the findings of this study is organized and summarized into the following folders, each containing its corresponding contents:

1. Cad files:

• Inventor File with parametric design to generate Kresling cells, in scale x1 (*.ipt). 
• Parasolid file, which can be scaled for 3D printing (*.x_b).

2. Abaqus inp files

• Example of Abaqus input file for FEA (*.inp). Case 8, RF=0.80, scale x3.

P.S. We provide an example of a simulation. If anyone is interested in other cases, please feel free to contact us and request them via email at diego.misseroni@unitn.it.

3. Experimental raw data:

• Raw experimental data taken from Messphysik μ-strain loading frame machine (from ZwickRoell, 0.01 µm stroke measurement resolution). The applied Load F and displacement u were measured with a AEP TYPE F1-1kN load cell and with a displacement transducer mounted internally to the testing machine, respectively.

4. MATLAB notebook files:

• Calculation of Prony parameters from stress relaxation tests using a Prony series function (Levenberg–Marquardt method).
• Initial sizing of Kresling cells to determine whether the selected geometrical configuration is bistable. The 5-parameters method was used.

5. Excel files:

• Summary of FEA and Experimental Load paths and energy landscapes, used for generating Fig.2,3,4.
• Summary of Material characterization data from uniaxial and stress relaxation tests.
