Scope of the Workshop
The Workshop aims at introducing new non contact full-field measurement techniques and at focusing on their benefit to Experimental Mechanics in Materials and Structural Engineering. The improvement in data acquisition and data treatment with microcomputers has lead to an increasing use of new optical measurement methods, less and less intrusive and more and more efficient in the sense they now can provide millions of measures every few seconds. The main question is how to estimate the errors that have been made during the measurement process and to deal with such a huge amount of values. It is obvious that some basis in optics cannot be totally avoided, especially to perform correct calibration of the optical devices.

The presentations will first present these methods on a general basis and discuss the pros and cons of the techniques the most in use. New application in Mechanical Identification will then be introduced and specific examples treated.

 

Proceedings
A booklet combining the PowerPoint files of the presentations will be provided to the participants to the workshop. Extended papers based on the presentations could be issued in the journals of the societies after the workshop.

 

Fees including the booklet of the proceedings and lunch
80 euros,
60 euros for members of the organizing and supporting societies: BSMEE, AFM, Promoptica, Cmoi,
free for students (does not include lunch).

Round Table and adjourn  
The round table will focus on both the benefit of those new methods, which tend to become new standards for mechanical testing, and the needs to give engineers and researchers in Mechanics the capability to use at best those techniques.
