Technical Examples of Building on the Work of Others to Fulfill Your Purpose
(With Attributions to David Ewins and other IMAC Colleagues)

The theme “Standing on the Shoulders of Giants” is explored over my structural dynamics career. Some sage technical and philosophical advice from one of the giants of modal testing, David Ewins, is included to provide a technical boost to early career experimentalists. The history of building upon the work of several IMAC colleagues is related in the career-long use and exploration of the modal filter. This amazing principle has provided technical advancement and understanding in the sub-disciplines of force reconstruction, modal parameter estimation, experimental dynamic substructuring, nonlinear analysis and impedance matched multi-axis test planning. The conclusion is stimulated once again from a David Ewins premise. I extend this to the listener in an exhortation of purpose. When this pilgrim looks back over a long career, he can clearly see mileposts of purpose that were not as evident when they were originally passed.
Randy Mayes began his structural dynamics career as a finite element analyst using NASTRAN in 1979 at Sandia National Laboratories. He moved into the modal testing group in 1989 where he worked until retirement in 2020. He has always enjoyed the friendly IMAC conference of SEM. An ElliptiGO stand-up bicycle and a classical guitar provide great hobbies. His favorite paraphrased scripture from the book of James is “Count it a joyous opportunity when you have an interruption or obstacle to your plans. As you patiently watch God work it out, He will change you into a fantastic person”.
