For example, the lab houses a 40-horsepower screw compressor, made from heavy-duty steel parts bolted together.

He is working to compare those measurements with computer models in hopes that one day he will be able to account for nonlinear vibrations like these. The ability to properly account for nonlinearity would be useful for all sorts of industries.

He is developing computer models that he hopes will eventually be able to predict the nonlinear vibration damping of structures like this, or anything that is assembled with bolts—which is everything from rockets to bridges.
