AEM Seminar:
Predicting Damage in Aerospace Structures Due to Adverse Weather Encounters
Abstract:
There
is renewed interest in hypersonic flight with applications in defense
and civilian aerospace. 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.
