Welcome to the IMR GitHub Org.!
Inertial Microcavitation high strain-rate Rheometry (IMR) correlates the evolution of the bubble pressure and the stress field in the material with the resulting kinematics, namely the change in bubble radius over time, which is recorded via high-speed videography.
IMR originated from the Franck Lab at the University of Wisconsin-Madison. The first paper discussing IMR is located here. Now, it is developed and maintained by the groups of Professors (alpha by last).
There is a user guide and documentation to get you started. Another good resource is the README.md in the repositories.
If you have questions, you can contact the maintainers (e.g., Jon Estrada) and/or request to join the IMR Slack workspace.
