S. Mark Spearing
Professor of Aeronautics and Astronautics
Research
Interests
Prof.
Spearing's core research activity is the development of mechanism-based
models and design approaches for the failure of advanced materials to
allow their use in high performance systems. These models and approaches
are presented and actively communicated in a form suitable for use as
structural design tools, in aerospace applications and elsewhere. Professor
Spearing is currently pursuing two interrelated research thrusts, namely:
materials and structures for power microelectromechanical systems microengines,
microrockets, micro-hydraulic transducers, and micro-chemical power generation)
and mechanism-based modeling of failure of engineered materials. His
research activities include modeling, using closed-form and numerical,
solid mechanics and fracture mechanics solutions supported by appropriate
mechanical testing and observational techniques. The
emphasis of both thrusts is on conducting research on technologically
important topics in conjunction with partners in industry, academia and
government agencies.
Professor Spearing is co-director of TELAC (The Technology Laboratory for Advanced Composites) and is a member of GTL (The Gas Turbine Laboratory) and AMSL (The Active Materials and Structures Laboratory).
