There is renewed interest in hypersonic flight with defense and civilian aerospace applications. Nontrivial chances of weather encounters with airborne particles (raindrops, ice particulates, volcanic ash) exist at lower altitudes. Predicting structural damage due to raindrops at hypersonic velocities is an open problem owing to the complex multiphysics involved.

This talk will first describe the physics of the high-speed droplet impact and then demonstrate a computational solid mechanics approach, peridynamics, for damage predictions. Droplet-shock layer interactions, coupling with computational fluid dynamics, 2D vs. 3D, and other relevant topics will be discussed.
