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…
