Geomechanics research in Microgravity environments

On November 19th, four researchers affiliated with the Computational Geomechanics Group flew on a microgravity flight out of Melbourne, FL.  The microgravity environments are achieved by flying a series of parabolas, where an increased gravity state is immediately followed by a decreased state with the specific gravity levels controlled by the shape of the parabolas.  Over the course of 3 hours and 25 parabolas, the group successfully performed soil strength tests at 4 different gravity levels (Earth, Mars, Moon, zero gravity).  The tests were conducted on a specially designed apparatus built in collaboration with researchers at Caltech, JPL, and MIT.  The results will be used to better understand soil mechanics and drilling processes on a variety of bodies in the solar system, with the results especially pertinent to current NASA objectives of landing on an asteroid and Mars. 11.23.15

Graduate Student Wins Young Stress Analyst Competition

Mechanical and civil engineering graduate student Ryan Hurley who works with Professor José Andrade has won the the BSSM (British Society for Strain Measurement) Young Stress Analyst Competition at the 16th International Conference on Experimental Mechanics (ICEM.16). The competition is an annual competition that is intended to encourage and reward young practitioners in the field of experimental mechanics. Ryan was among six finalists representing universities in Belgium, Poland, France, and the USA, who were selected from 34 applications by a panel of experts. The finalists presented their work during the ICEM.16 conference and were judged by a panel of leading researchers. [YSA Competition Information. 07.17.14

Professor Andrade Featured on “You’re the Expert”

José E. Andrade, Professor of Civil and Mechanical Engineering, and his research on earthquake-induced liquefaction and granular materials was featured on You're the Expert, a new live show and public radio program. The show uses comedy to make academic research more accessible and exciting. During the live taping at Caltech three comedians tried to guess what Professor Andrade studies. Then they interviewed him about his work, why it's important, and what's new and exciting in his field. [Audio podcast - Granular Materials] 3.16.14

Seeing the World in a Grain of Sand - Watson Lecture

For almost 80 years, the California Institute of Technology has offered its Earnest C. Watson Lecture Series. The late Caltech physicist Earnest Watson conceived the series as a public lecture program designed to explain science to the local community. 

In this Watson Lecture, Prof. José Andrade describes the cutting edge research done by his group at Caltech (Computational Geomechanics Laboratory), and the relevance of this work, as well as, some important applications. All in a very simple, didactic and interesting way.

Compaction Bands in Sandstone are Permeable

José E. Andrade, Associate Professor of Civil and Mechanical Engineering, and colleagues have analyzed X-ray images of Aztec sandstone and revealed that compaction bands are actually more permeable than earlier models indicated. Their paper provides the first permeability calculations based on actual rock samples taken directly from the field in the Valley of Fire, Nevada. They conclude that these formations are not as impermeable as previously believed, and that therefore their ability to trap fluids—like oil, gas, and CO2—should be measured based on 3D images taken from the field.
