Research
Interests
Dr.
Bettig's research is motivated by the desire to create better designs,
faster. In the Design and Manufacturing Computations Lab, Bettig
and students develop theories and testbed software to automatically
synthesize and simulate novel product designs. To query and manipulate
design geometry at a high level, Bettig has developed a data structure,
the "Design Exemplar,” that provides a unified, mathematical
representation for disparate types of engineering knowledge and
operations.
Bettig
and his students have developed theories and software for a variety
of applications, including finite element/finite difference simulation
of hydro-generator rotordynamics, tethered spacecraft vibration
visualization, variational geometric/algebraic constraint solving,
declarative component design, topology optimization of smart structures,
optimization using distributed computing, and an object-oriented
CAD software framework to integrate design tools. Bettig also has
experience as an aerospace design engineer.
