This Project Grant award from the National Science Foundation (NSF) Division of Civil, Mechanical, and Manufacturing Innovation under the NSF Engineering program (CFDA 47.041) supports research to characterize, model, and predict the mechanical response of non-uniform soft materials subjected to rapid bubble collapse and oscillation. The total funding amount is $194,800 for the period of June 1, 2023 to May 31, 2026. The research aims to leverage quantities surrounding asphericity, which was previously regarded as a problem, as a critical metric for assessing local material gradients. The experimental setup involves a multi-perspective, ultra-high-rate microscopy platform for characterizing UV-tunable hydrogels using bubble kinematics and full-field deformations. Concurrently, numerical methods will establish a suite of baseline problems to be used in an inverse calibration approach to develop a fast reduced-order model for describing both material behavior and gradients. The expected outcomes include a methodology for producing linearly graded hydrogels, a database of ultra-high-rate, finite viscoelastic hydrogel behavior, and an upgraded inverse-calibration procedure and reduced-order approach for fast rheology.
