Two International Aerospace Leaders Receive von Kármán Wings Award

11-19-18

This year's International von Kármán Wings Award honorees were Jean-Yves Le Gall, president of the French Centre National d'Études Spatiales and A. S. Kiran Kumar, Vikram Sarabhai Professor and former chairman of the Indian Space Research Organization and former secretary of the Indian Department of Space. The ceremony also featured the presentation of two scholarships to honor top graduate students in aerospace. "This event is absolutely unique," said Professor Ares Rosakis and chairman of the the Aerospace Historical Society. "What makes it so is that it reflects the phenomenal international connections between Caltech, GALCIT, JPL, and NASA and it also highlights the true international nature of aerospace. More importantly, it gives us the opportunity to take a glimpse at the future by also honoring our own students who will one day define the future of space science and the future of space technology."

How Friction Evolves During an Earthquake

08-15-17

Professor Ares Rosakis, and colleagues including Professor Nadia Lapusta and Research Scientist Vito Rubino, are studying the way friction changes along a fault during a seismic event by simulating quakes in a lab. "Our unique facility … allows us for the first time to study friction point-wise and without having to assume that sliding occurs uniformly, as is done in classical friction studies," Rosakis explains. Professor Lapusta adds, “some numerical models of earthquake rupture … have used friction laws with slip-velocity dependence… It is gratifying to see those formulations validated by the spontaneous mini-earthquake ruptures in our study. " [Caltech story]

Earthquakes Can Make Thrust Faults Open Violently and Snap Shut

05-01-17

Ares J. Rosakis, Theodore von Karman Professor of Aeronautics and Mechanical Engineering, and colleagues at Caltech and École normale supérieure in Paris have discovered that fast ruptures propagating up toward the earth's surface along a thrust fault can cause one side of a fault to twist away from the other, opening up a gap of up to a few meters that then snaps shut.
