Programming the energy landscape of 3D-printed Kresling origami via crease geometry and viscosity

This release includes the cad files, Abaqus inp files, MATLAB notebooks, raw experimental data and excel files used to elaborate the plots associated with the paper: 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 [e-mail]. 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.
