John O'Callahan has written many papers over the years covering analytical model reduction techniques, structural dynamic modification, estimation of rotational dof, correlation of analytical / ...

FEA can be a useful tool for sizing up resonance problems. Mention FEA and the first things that comes to an engineer's mind are stress and deflection. But FEA can do more than that. It can also show ...

The proposed intelligent analysis method bridges high-fidelity modeling and computational efficiency. It uses an iterative algorithm to identify optimal mode shapes ...

The Structural Dynamics and Acoustic Systems Laboratory (SDASL), formerly the Modal Analysis and Controls Laboratory, focuses on research related to analytical and experimental problems in the areas ...
