|Uncertainty Quantification in Digital Image Correlation||
22 Feb 2017
|The National Physical Laboratory, Hampton Rd, Teddington TW11 0LW, UK.||Seminar|
Dr Richard Burguete, NPL
Dr Dave Hollis, BSSM
The seminar is aimed at engineers, physicists and scientists with a background in mechanics of materials and\or mechanical testing wishing to learn more about uncertainty quantification in DIC measurements.
Digital Image Correlation (DIC) is an extremely popular measurement tool utilised widely in experimental mechanics. By virtue of the optical technology it employs, it is easy to deploy and can acquire data where other techniques cannot. It is also very easy to gather full-field data quickly. However there is still a lack of understanding surrounding the uncertainties associated with DIC measurements:
- What are the sources of error in DIC measurements?
- How can we quantify the uncertainties reliably?
- How do I use this uncertainty information?
- How does it propagate into derived data?
- Does uncertainty quantification (UQ) really matter?
This event aims to address these questions. It may not arrive at all of the answers but the objective is to share current practices and perspectives around this extremely important subject. Through a host of well-known speakers you will learn about uncertainty quantification; it’s history, importance, and state-of-the-art approaches. The event will also have a session where you will be encouraged to share your ideas and current approaches to UQ in DIC measurements.
There will be an exhibition of instruments related to the techniques presented.
