How does it amplitude and frequency response work in cracks detection?

03 August 2022 1 8K Report

I am currently working on my project of crack detection in cantilever beams using an Ansys, and I did modal analysis and harmonic response to find the natural frequencies and frequency response of the deformation.

I have found the maximum amplitude of all 6 modes and how does it really work in crack detection?

amplitude gets lower when frequencies get higher.?

Hi,

Thank you so much for your response and its so helpful.

I need to know about how it works with cracks detection?

absolutely the natural frequencies of the healthy and unhealthy varies.

also amplitude of the healthy and unhealthy varies as well. I need a clear idea about detection working?

it would be helpful if someone could clarifying this..
