    Vibration modes for fixed-fixed beam with added mass

    Thanks for the input everyone! I went out and borrowed a copy of Blevins - quite a helpful resource, actually. However, the closest it comes to helping is a list of different scenarios for slender beams with concentrated mass - and again, only provide the fundamental natural frequency. Most of...

    Vibration modes for fixed-fixed beam with added mass

    I have been stumped on this for several days now, wondering if someone might be able to point out some obvious error in my thought process. So, the issue seems simple enough. I have a fixed-fixed beam, with known E, I, A, density. However, there is an added mass at a certain distance (not...

    Dynamic Response - resonance

    I am currently trying to model forced vibration on a simple cantilever beam. I am looking to model a resonance scenario, and was wondering if anyone had some suggestions on how to do this in ABAQUS. Currently, I have determined the natural frequencies and modal shapes of the beam (using the...
