Datenpaket: Contributing research data to the doctoral thesis "On Topological Mechanics of 3D Chiral Metamaterials"

General Information

This repository contains additional research data contributing to the doctoral thesis "On topological mechanics of 3D chiral metamaterials" by J. Köpfler. Further data of related publications (DOIs: 10.1002/adma.202103205 and 10.1103/PhysRevApplied.11.034059) can be found in the corresponding repository (DOI: 10.5445/IR/1000135066).

Folder structure:

The data in each folder is sorted in subfolders corresponding to the chapters of the doctoral thesis

Fabrication

• contains the 3D printing files for the microstructure casts (double-sided support mirror structure) and a file that was used to design the 3D microcast

Calculations

• contains the files for the Matlab scripts and COMSOL files for the FEM-calculations

Experiments

• contains the image series that was acquired for the evaluation of the resonance of the double-sided support mirror structure
• contains the scripts to extract displacement data and generate the resonance plots etc.

Experimental data treatment:

Image cross-correlation was performed using the "grid_generator_" functions on the digital images, followed by the "automate_images_" functions. The resulting datasets "validx.dat" and "validy.dat" for the tracked x- and y-displacements are loaded, processed, collected, and plotted via the specific "combine_parts_" functions in the individual measurement folders.
