  • Daniel DeBra

    Daniel DeBra

    Edward C. Wells Professor of Engineering, Emeritus

    BioProfessor DeBra collaborates with Stanford physicists on three projects: Gravity Probe-B (GP-B), Space Test of the Equivalence Principle (STEP), and the vibration isolation of a gravity-wave antenna (LIGO). These involve satellite control of attitude and translation and the development of instruments of extraordinary precision and accuracy. In GP-B gyroscopes were successfully orbited in 2004. They have been compared to stars to an accuracy approaching a nanoradian. In STEP the orbital performance promises improvements of a million in testing the equivalence of inertial and gravitational mass. (It is currently in a hiatus of funding.) Professor DeBra's interests in precision engineering extend to manufacturing where his students' work developing "quiet hydraulics" in the 1990s has more recently been applied to the vibration isolation of the optical systems of LIGO.

    BioProfessor Christensen's research is concerned with the mechanics of materials. The behavior of polymers and polymeric fiber composites are areas of specialization. Of particular interest is the field of micro-mechanics that focuses on materials' functionality at intermediate-length scales between atomic and the usual macro scale. Applicable techniques involve the methods of homogenization for all types of composite materials. The intended outcomes of his research are useful means of characterizing the yielding, damage accumulation, and failure behavior of modern materials. A related website has been developed to provide critical evaluations for the mathematical failure criteria used with the various classes of engineering materials. Most of these materials types are employed in aerospace structures and products.
