Just to clarify my understanding of the subject: In a typical modal impact test you strike the object with a hammer and measure both the input and output responses from the hammer and object respectively. Since the impact is not a pure impulse it is treated as a harmonic load and frequency...

As part of a research project I will be load testing a beam in my school lab. I have been asked to try and determine the damping of the beam as part of this project and I was considering conducting a modal impact test. I am not very familiar with structural dynamics and wanted the opinion of...
