Srivatsan Hulikal Wins Seismo-Engineering, Prediction, and Protection Prize


Graduate student, Srivatsan Hulikal, was the recipient of the the 2015 Demetriades - Tsafka - Kokkalis Prize in Seismo-Engineering, Prediction, and Protection. In his thesis, Dr. Hulikal successfully took on the multifaceted and challenging problem of linking macroscopic frictional properties of interfaces to their micromechanics. His advisor Professor Lapusta explains, “Understanding this connection is key to addressing fundamental problems in seismo-mechanics and seismo-engineering, such as creating predictive physical models of earthquakes.”

An Earthquake Warning System in Our Pockets?


Thomas H. Heaton, Professor of Engineering Seismology, and colleagues’ recent study suggests that all of our phones and other personal electronic devices could function as a distributed network, detecting any ground movements caused by a large earthquake, and, ultimately, giving people crucial seconds to prepare for a temblor. "Thirty years ago it took months to assemble a crude picture of the deformations from an earthquake. This new technology promises to provide a near-instantaneous picture with much greater resolution," says Professor Heaton. [Caltech story]

Heat Transfer Sets the Noise Floor for Ultrasensitive Electronics


Austin Minnich, Assistant Professor of Mechanical Engineering and Applied Physics, and colleagues have identified a source of electronic noise that could affect the functioning of instruments operating at very low temperatures, such as devices used in radio telescopes and advanced physics experiments. The team's findings also suggest that it may be possible to develop engineering strategies to make phonon heat transfer more efficient at low temperatures. For example, one possibility might be to change the design of transistors so that phonon generation takes place over a broader volume. "If you can make the phonon generation more spread out, then in principle you could reduce the temperature rise that occurs," Professor Minnich says. "We don't know what the precise strategy will be yet, but now we know the direction we should be going. That's an improvement." [Caltech release]

Seismology and Resilient Infrastructure


Domniki Asimaki, Professor of Mechanical and Civil Engineering, is interested in the behavior of geotechnical systems under the influence of forces such as wind, waves, and seismological activity. Using this information, she hopes to make predictive computer models that can lead to the design of an infrastructure that is resilient to natural and man-made hazards. Her work also relates to the harvesting of wind energy and she explains, “People like myself with an engineering background, but also with scientific curiosity, can work in areas like this and set the performance and design standards from scratch. But because the energy-harvesting industry is just starting out, we need to make it innovative while still financially feasible.” [Interview with Professor Asimaki] [ENGenious article]

Ceramics Don't Have To Be Brittle


Julia R. Greer, Professor of Materials Science and Mechanics, and her colleagues are on the path to developing materials that possess unheard-of combinations of properties. "Ceramics have always been thought to be heavy and brittle," says Professor Greer. "We're showing that in fact, they don't have to be either. This very clearly demonstrates that if you use the concept of the nanoscale to create structures and then use those nanostructures like LEGO to construct larger materials, you can obtain nearly any set of properties you want. You can create materials by design." [Caltech Release]

Professor Ravichandran Receives SEM Murray Lecture and Medal


Guruswami (Ravi) Ravichandran, John E. Goode, Jr. Professor of Aerospace and Professor of Mechanical Engineering, and Director of GALCIT, has been awarded the Society of Experimental Mechanics (SEM) William M. Murray Lecture and Medal. He delivered the 2014 Murray Lecture entitled, Three-Dimensional Quantitative Visualization: Application to Studying Cell-Matrix Interactions, on June 3, 2014 during the SEM Annual Conference and Exposition on Experimental and Applied Mechanics. The award was made in recognition of his pioneering contributions in experimental mechanics of deformation, damage and failure of materials under multiaxial dynamic loading. The Murray Lecture is the highest distinction awarded by SEM and is the prestige lecture of its annual conference.  The Murray Lecture was established in 1952 in honor of the first President of SEM, William MacGregor Murray who was a Professor and Executive Officer of Mechanical Engineering at MIT.

Professor Greer Named One of Most Creative People in 2014


Julia R. Greer, Professor of Materials Science and Mechanics, has been named one of Fast Company's Most Creative People in 2014. "What if you could fabricate nanotrusses--materials made up of tiny, intricate geometric structures linked together--in a way that might resemble, say, the webwork of the Eiffel Tower?" describes Professor Greer.
