Data, analysis code and simulation code for "Geometric control of topological dynamics in a singing saw"

This repository contains all experimental data and source code required to reproduce the figures in the paper Shankar S, Bryde P, Mahadevan L. 2022 Geometric control of topological dynamics in a singing saw. Proceedings of the National Academy of Sciences USA. also available as a preprint at Shankar S, Bryde P, Mahadevan L. 2021 Geometric control of topological dynamics in a singing saw. arXiv preprint arXiv:2108.10875. The dataset contains the following folders: experiments: Contains the experimental data (raw audio) and data analysis code to reproduce the experimental components of the figures: Fig. 1D, Fig. 3C-D, and Fig. S1A-C.The experimental data is contained in the J-bow, J-mallet, S-saw and S-mallet subfolders. simulations: Contains the code to run the numerical simulations and reproduce Fig. 2B-E, Fig. 3A-B, Fig. S2A-B, and Fig. S3A-D.The simulation code is written in Python and organized as follows:The shells folder contains finite element simulation code based partly on the FEniCS-Shells library1 and employs the FEniCS Project finite element problem solving environment. The saw folder contains scripts that perform the numerical simulations and produce the graphs. More information can be found in the README. --- 1Simple and extensible plate and shell finite element models through automatic code generation tools, J. S. Hale, M. Brunetti, S. P. A. Bordas, C.
