Thermal plugins from the EikoTwin suite
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 software and DT thermal plugin…
EikoTwin DIC and the measurement of small strains
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 to perform realistic simulations. The objective is…
The Batch mode: a new EikoTwin DIC plugin
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 automation of the data processing ensures significant…
IRT Saint-Exupéry trusts us with our software : EikoTwin
Ludovic Barrière is Project Manager at IRT Saint-Exupéry, he tells us about his experience with our software: EikoTwin DIC and EikoTwin Digital Twin. The software EikoTwin DIC in a few words EikoTwin DIC is an image processing software dedicated to the link between measurements and numerical simulations. It uses a patented measurement technology to provide…
Safran Ceramics trusts EikoSim with the “Thermal” plug-in
Benjamin Lacombe is a Mechanical Design Engineer at Safran Ceramics. 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 high-temperature solutions for tomorrow’s aircraft. We conduct a large number…
Technical functionality: selection of the measurement mesh
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 results will be calculated. It is therefore essential to select…
Simulation validation with EikoTwin DIC
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 mesh. Thus, you will be…
EikoTwin DIC 1.3 is available!
On the menu of the main improvements of this first update of the year 2021 : Reduced computation times and lighter results. Emphasis has been placed on computation performance and storage in EKT files. New “Batch” mode. It will allow you to perform a series of calculations directly with EikoTwin DIC. Do not hesitate to…
Hybrid calibration : a robust alternative to self-calibration
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 correspondence between points of the model and…
Mastering self-calibration with EikoTwin DIC
To provide accurate Digital Image Correlation (DIC) results, the EikoTwin DIC software must first calibrate the camera system. This is made using images of the structure in its reference state (unloaded). Using these images, the software determines the intrinsic parameters (the cameras focal lengths, optical centers, skews) and extrinsic parameters (camera positions and orientations in…
