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.

New President of the French Academy of Sciences

02-02-17

Alumnus Sébastien Candel (PhD '72) has been elected as president of the French Academy of Sciences (Académie des sciences, Institut de France). The Academy, which was created in 1666, is committed to the advancement of science and advises government authorities on scientific issues.  Candel obtained his PhD in mechanical engineering and applied mathematics from Caltech and is a receipient of the Caltech Distinguished Alumni Award for his contributions to aerospace.

Modular Space Telescope Could Be Assembled By Robot

09-28-16

Professor Sergio Pellegrino and colleagues including Professor Joel Burdick, are proposing a space observatory with a 100 meters diameter primary mirror. Their design calls for the use of more than 300 deployable truss modules that could be unfolded to form a scaffolding upon which a commensurate number of small mirror plates could be placed to create a large segmented mirror. In this concept, a spider-like, six-armed "hexbot" would assemble the trusswork and then crawl across the structure to build the mirror atop it. [Caltech story]

Caltech Mechanics Reunion at International Conference

09-12-16

More than 70 students, faculty, friends, and alums from GALCIT and MCE attended a Caltech Mechanics Reception during the 2016 International Conference on Theoretical and Applied Mechanics, which was held in Montreal on August 23, 2016. Attendees ranged from current students to a 1965 Mechanical Engineering undergraduate. All appreciate the opportunity to reconnect with the extended Caltech mechanics family.

The Utility of Instability

08-08-16

Professors Dennis M. Kochmann and Chiara Daraio along with colleagues from Harvard have designed and created mechanical chains made of soft matter that can transmit signals across long distances. Because they are flexible, the circuits could be used in machines such as soft robots or lightweight aircraft constructed from pliable, nonmetallic materials. "Engineers tend to shy away from instability. "Though there are many applications, the fundamental principles that we explore are most exciting to me," Kochmann says. "These nonlinear systems show very similar behavior to materials at the atomic scale but these are difficult to access experimentally or computationally. Now we have built a simple macroscale analogue that mimics how they behave." [Caltech story]

Tyler Okamoto Receives 2016 Henry Ford II Scholar Award

06-01-16

Mechanical Engineering student Tyler Okamoto, mentored by Professor Sergio Pellegrino, is a recipient of the 2016 Henry Ford II Scholar Award. He is working with Professor Pellegrino’s team to build an autonomous reconfigurable space telescope using multiple nanosatellites that align in space to create a camera and mirror assembly. The Henry Ford II Scholar Award is funded under an endowment provided by the Ford Motor Company Fund. The award is made annually to engineering students with the best academic record at the end of the third year of undergraduate study.

Professor Rosakis Elected to the National Academy of Sciences

05-03-16

Ares J. Rosakis, Theodore von Karman Professor of Aeronautics and Mechanical Engineering, has been elected to the National Academy of Sciences (NAS). His research interests span a wide spectrum of length and time scales and range from the mechanics of earthquake seismology, to the physical processes involved in the catastrophic failure of aerospace materials, to the reliability of micro-electronic and opto-electronic structures and devices. The National Academy of Sciences is a private organization of scientists and engineers dedicated to the furtherance of science and its use for the general welfare.[Caltech story] [List of NAS members]
