Their findings were recently published in the Journal of Fluid Mechanics, and for the first time demonstrate the unique differences in water impact behavior of rigid and elastic bodies.

"Rigid and elastic materials interact with the water surface quite differently," said Randy Hurd, a PhD candidate at USU and lead author on the study. "When an elastic body impacts the surface, the material deforms and oscillates significantly which changes the water-impact physics compared to a rigid body."

Hurd - Team - High-speed - Cameras - Spheres

Hurd's team used high-speed cameras to record elastomeric spheres dropping into a tank of water. At 2,000 frames per second, the footage revealed the unique splash curtains and air-filled cavities that form after impact. The group used the images to track the position and deformation of...
