In cold spray, the presence of jetting has been linked to bonding. However, the origin of the material instability preceding jetting is highly debated. High-speed impact of hyperelastic material shows similar instability. We theorize that the origin of this instability in hyperelastic material is similar to the origin of instability in cold spray particles. In current work, Abaqus Finite Element Analysis software is being used to examine the dependence of this instability on various physical phenomena, including conservation of volume, inertial and shock effects, and strain-rate effects in the impact of a modeled macro-scale hyperelastic particle. This approach allows different physical effects to be evaluated separately and in combination to isolate the key contributors to the instability. Using models to relate the response of a macroscopic particle also opens a novel avenue for experiments on a length and time scale that allows much more detailed measurements.
