bubbles deforming under high strain-rates. In this work, we will evaluate IMR for a complete finite deformation range and
analyze its performance in polyacrylamide.
2.5 Conclusion
This study will test the limitations of our current IMR model to identify critical stretches at the transition from viscoelastic
to inelastic material behavior, as well as provide new experimental methods for controlled bubble amplitude modulation. The
experimental acquisition of a full finite deformation regime will lay the foundation for the incorporation of inelastic material
into the theoretical framework. Studies such as energy loss through the material, asphericity, rupture, wrinkling, and more
may be included ultimately improving our fundamental understanding of the high-rate deformation behavior of soft materials and improve our ability to predict constitutive material properties and material performance.
