Mechanical regularization in EikoTwin DIC
By Lucas Angénieux, Research engineer at EikoSim In EikoTwin DIC, the calculation of displacement fields is performed on the simulation mesh. However, as this mathematical problem is by nature ill-posed, there is a mechanical regularization parameter that allows the user to add mechanical conditions to the field measurements. Contrary to most digital image correlation software, at…
Digital image correlation for automotive structures
By Floriane Soulas, R&D Engineer at EikoSim Context In the context of monitoring large-scale production automotive parts, many parts are subjected to repeated tests to ensure their integrity once they are put into service. Thus, the test that we address in this paper is dedicated to the “gust of wind” tests of an opening structure (see…
Thermal plugins from the EikoTwin suite
By Clara Minguet, Research engineer at EikoSim In order to meet the specific needs of customers and to extend the use of the EikoTwin software suite to other fields of activity, EikoSim has developed two new optional plugins: the DIC and DT thermal plugins. As their names suggest, DIC thermal plugin can be used in…
EikoTwin DIC and the measurement of small strains
By Lucas Angénieux, Research engineer at EikoSim Innovation in the automotive industry Innovation is at the heart of the automotive industry: autonomous vehicles, shared mobility, advanced equipment, etc. In order to reinvent themselves and remain competitive, it is necessary for automotive industries to innovate and develop new technologies. It is therefore essential for these companies…
The Batch mode: a new EikoTwin DIC plugin
By Clara Minguet, Research engineer at EikoSim In order to continuously improve the features offered by EikoTwin DIC software, EikoSim has developed a new optional plugin: the Batch mode. It enables to launch, through a configuration file prepared beforehand, the pre-calibration, calibration and displacement measurement for several EikoTwin DIC projects in EKT format. This partial…

He tells us about his experience with EikoTwin DIC and the development of the “Thermal” plug-in. « I work at Safran Ceramics, Safran group’s center of excellence for high-temperature composites. We are in charge of developing…
Technical functionality: selection of the measurement mesh
By Clara Minguet and Lucas Angénieux, Research engineers at EikoSim On EikoTwin DIC, the measurements are directly expressed on the simulation mesh. In order to choose which areas of interest for the test are visible to the camera(s), the so-called measurement mesh must first be selected. Indeed, this mesh will be the one where the…
Simulation validation with EikoTwin DIC
By Florent Mathieu, Ceo of EikoSim Simulation validation with EikoTwin DIC rely heavily on image processing. Image analysis methods provide full-field test data, that can be used to validate and improve your simulation. Using the unique method of “Model-Based testing”, EikoTwin DIC allows to measure displacements and strains of the observed parts directly on the simulation…
Hybrid calibration : a robust alternative to self-calibration
By Pierre Baudoin, R&D engineer at EikoSim Introduction This article is written as a complement to the article on good calibration practices recently published on our website. In general, it is very often possible to calibrate the camera system in EikoTwin DIC thanks to the knowledge of the geometry of the part, and of the…
