Ares J. Rosakis,

Graduate Aerospace Laboratories, known as (GALCIT), and formerly known as Guggenheim Aeronautical Laboratory
, and was the Otis Booth Leadership Chair, of the Division of Engineering and Applied Science.

Education and career

Ares Rosakis graduated from

He served as Interim Director (2003-2004) and Director (2004-2009) of the Graduate Aerospace Laboratories (

GALCIT
) formerly known as the Guggenheim Aeronautical Laboratories.

In 2005, Rosakis was a Distinguished Visiting Professor in the Dept. of Terre Atmosphére-Océan,

École Normale Supérieure Paris, France. In 2008, he held the prestigious Astor Visiting Professorship at the University of Oxford. In early 2018 he held a Distinguished Simpson Visiting Professorship at Northwestern University and a Distinguished Nanyang Visiting Professorship[2] at Nanyang Technological University
(NTU) in Singapore.

Between 2009 and 2015, he was Chair of the Division of Engineering and Applied Science (EAS) at Caltech. In June 2013, Rosakis was named the F. Otis Booth Leadership Chair in addition to his academic, Theodore von Kármán, chair. Rosakis was the first holder of such a Leadership Chair at Caltech. Between 2009 and 2015 he also served as a member of all three of Caltech's Governing bodies, the Institute's Academic Council (IACC), the Institute's Administrative Council (IAC), as an Ex-Officio Member of the Institutes’ Faculty Board and between 2005 and 2014 as member of

JPL
’s Advisory council.

Rosakis is a member of both the National Academy of Sciences[3] (NAS), and the National Academy of Engineering[4] (NAE). As such, he is one of only seventy living Americans to be elected to membership in both the NAS and the NAE branches of the US National Academies. He has also been elected to the American Academy of Arts and Sciences[5] (AAA&S) as well as five more Academies in Europe and India: Indian National Academy of Engineering (INAE), Academia Europaea (AE), European Academy of Sciences and Arts (Academia Scientiarum et Artium Europaea), Academy of Athens (National Academy of Greece), European Academy of Science (EUAS).

Honors and awards

Rosakis has been honored with various recognitions in many branches of Engineering and Science including, Reliability of Materials, Optics and Instrumentation design, Failure of Solid Materials with applications in micro-electronics, Aerospace and Civil Engineering structures and in Earthquake Source Mechanics.

In the late eighties, Rosakis introduced the concept of "laboratory earthquakes"

digital image correlation (DIC) and laser velocimetry as diagnostics. The fault systems are simulated using two photoelastic plates held together in frictional contact. The far field tectonic loading is simulated by pre-compression while the triggering of dynamic rupture (spontaneous nucleation) is achieved by suddenly dropping the normal stress in a small region along the interface. The frictional interface (fault) forms various angles with the compression axis to provide the shear driving force necessary for continued rupturing. Rosakis and his co-workers, investigate the characteristics of rupture, such as rupture speed, rupture mode, associated ground motion under various conditions such as tectonic load, interface complexity and roughness.

A Dynamic shear rupture, is captured propagating (left to right) along a frictional interface between two elastic plates at supershear speeds (speeds exceeding the shear wave speed of the solid). The images are created by using high-speed, digital photography (106 frames/second) and Digital Image Correlation (DIC). DIC identifies gray level patterns in small pixel subsets and tracks their motion (From: Rosakis, Rubino and Lapusta, JAM, 2020, [DOI: 10.1115/1.4045715]).

Both homogeneous and bimaterial interfaces (abutted by various elastic and damaged media) are investigated. Rosakis and his coworkers have been credited with the experimental discovery of the "intersonic" or "supershear

rupture" phenomenon. They also have investigated this new phenomenon in various engineering and geophysical settings involving shear dominated rupture in the presence of weak interfaces or faults. Their experimental discoveries of supershear rupture has refocused the attention of the geophysics community to the study of supershear earthquakes.

Another recent research interest for Rosakis is

JPL
's Small Particle Hypervelocity Impact Range (SPHIR) facility. By combining high speed photography, optical, spectroscopic and infrared techniques, including Coherent Gradient Sensing (CGS) interferometry, the dynamic perforation behavior involving crater morphology, debris and ejecta formation and solid/fluid/plasma transitions and interactions have been examined.
