Digital Image Correlation, how to choose your acquisition hardware?

By Team Eikosim | 5 October 2018

We have already seen together the principles of digital image correlation and the contributions of such measures. Today we will see how to choose its acquisition hardware so that it is adapted to the different use cases encountered. Image acquisition equipment means the cameras of course, but also the lenses, the lights, the mounting brackets…

Towards a better understanding of mechanicals tests thanks to DIC, with ALSTOM and CETIM

By Team Eikosim | 17 September 2018

Consistency of simulation and test data The consistency of test data and numerical results is paramount while carrying out the simulation-experiment comparison required to validate numerical simulations. First of all, mechanical tests need to respect the specifications laid out during their design: sample geometry, load path, location and orientation of the loading point, measurement points…

Digital image correlation: The contribution of the global method

By Team Eikosim | 17 August 2018

Why a “global” method? Digital image correlation consists in measuring a displacement field between a reference configuration and a deformed configuration. There are two large families of algorithms to make this measurement: the subset-based methods repeat a search operation for a battery of subsets positioned on a grid in the image. the global methods are…
