Abstract

This repository includes videos presenting experimental and simulation results for the torsion of a cellulose aerogel plate. These results are part of Lucas Mager's Ph.D. thesis. The experiment involves a long and thin aerogel plate that is clamped at both ends. A motor rotates one end of the specimen up to about 90 degrees, applying a torsion to the sample. Digital image correlation (DIC) is used to track the displacement of the aerogel plate. A multiscale simulation recreating the experimental setup has been computed for each timestep of the experiment. The torsion_displacement_iso.mp4 video presents a side-by-side comparison between the experimental and simulation results for the torsion test. An isometric viewing angle is used to display both experimental and simulation results. The coloring of the results illustrates the distribution of the deformation magnitude within the macroscopic geometries. Each second of the video shows ten timesteps computed in the simulation. The video given in torsion_displacement_xy.mp4 shows the same results, but it uses a different viewing angle. In this video, the viewpoint is set to focus on the xy-plane. The videos torsion_difference_xy.mp4 and torsion_rel_difference_xy.mp4 illustrate the distribution of the deviation between the displacement of the experimental and simulation results. For torsion_difference_xy.mp4, the coloring refers to the absolute magnitude of the difference between the displacement vectors of the experiment and the simulation and for torsion_rel_difference_xy.mp4, the coloring refers to the relative magnitude of the difference.
