Digital Image Correlation : test your software’s efficiency

By Team Eikosim | 11 July 2019

The quality of displacement fields measurements using Digital Image Correlation (DIC) depends on many factors which can be: Internal to the software (implementation of the algorithm, shape functions used for describing displacements, image interpolation method…); External to the software (quality of the speckle pattern, resolution of cameras, quality of calibration, …) In order to validate…

Designing a multi-camera structural test using pre-visualization

By Team Eikosim | 28 May 2019

Written by Matthieu Vitse Matthieu Vitse is a freelance scientific visualization expert. He has a PhD in computational mechanics from ENS Paris-Saclay, and his main activity now focuses on the post-treatment and visualization of large complex data simulations and experiments.

Instrumenting structural tests with imaging techniques: what benefits?

By Team Eikosim | 17 November 2018

It is quite simple to assess the benefits of using digital image correlation. For test engineers, DIC makes it feasible to prospect a larger area, to better understand the physical phenomena at stake by using a non-intrusive measuring method. For engineers working on numerical simulations, it is now possible to validate their models using vaster…

Digital Image Correlation – The basics

By Team Eikosim | 17 October 2018

Digital Image Correlation (DIC) is a measurement technique that processes pictures taken from cameras to track and record the surface motion of a deforming solid. In the mechanical engineering field, it has been widely used to monitor and process test data in both research and industrial contexts, for applications ranging from common material testing to…

The digital twin: bringing the real world into your simulations

By Team Eikosim | 17 October 2018

To estimate a structure’s mechanical behavior, proactive numerical studies have become common practice in mechanical engineering. Finite element modeling is now involved at all stages of the mechanical design project, from material behavior estimation (especially for composite materials), to intermediate assemblies, all the way up to structural computations. At each of the previous stages, simulations…

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…
