Can software simulations and structural health monitoring techniques accurately predict damage occurrence in aerospace structures using historical data(stiffness,damping and vibration measurements over a considerable period of time)


Are these techniques more suited to real time damage detection rather than damage prediction ?

For eg. SHM techniques such as parameter estimation using Frequency Response, or Non Destructive Inspection.

    $\begingroup$ I'm not sure it can accurately predict either. There are a lot of software packages out there that can model structural damage, but I don't know of any real-time damage detection system in use... $\endgroup$ – Ron Beyer Mar 7 '16 at 21:47

Yes it can be done. However, with the advent of technologies, you can also use the real time updates of the monitored system to understand it's health. In some cases where the historical data is not available, it becomes important to assess the structure's condition based on real time updates. I feel the following links could be of interest:

If you could elaborate on how it can be done this might be a much better answer. Also, it would be nice to disclose you are the first and second author on those articles you linked, otherwise this may be flagged as spam. $\endgroup$ – AEhere supports Monica Jul 8 '19 at 11:59
