Summary of Research
Bolted joints introduce significant uncertainty into the nonlinear dynamics of structures. Joints are required because it is not feasible to build large or complicated systems from a single piece of material. My research seeks to improve computational models of bolted structures that can then be used to improve designs of jointed connections. Better models and joint designs will reduce the current $2 billion annual cost of vibration testing of structures.
