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 ...

Modal testing of structures with closely coupled modes is a task performed very frequently. On many occasions, structures have modes that possess very similar resonant frequencies. In one such case, a ...

Aircraft structures are prone to vibrations due to their lightweight construction. In most cases, these vibrations are not critical. They decay due to damping effects from aerodynamic forces and ...

Many industries in the last decade successfully implemented finite-element analysis as a tool for product development. The success of FEA is now being followed by more widely used motion-analysis ...
