EikoTwin DIC
EikoTwin DIC is a digital image correlation (DIC) software program and system that links measurements and numerical simulations.
It uses a patented Digital Image Correlation technology to provide automatic test-simulation comparison.
It allows the efficient determination of model errors and the identification and resolution of error sources. EikoTwin is the only global FE-based digital image correlation software package built with simulation validation in mind.

Crash-test and image correlation: how to measure seat deformations and follow the dummy’s movements
Crash tests are crucial in developing and certifying products, especially for the automotive, aeronautical, and railway industries. These tests simulate collision or impact scenarios in order to evaluate the resistance and safety of products. Among the equipment used to perform these tests is the reverse catapult, which is a device that projects an object, in…
Digital Image Correlation (DIC) for vibration analysis
Digital Image Correlation (or DIC) is well-known for its static applications, but under the right circumstances, it is equally applicable to vibration testing. Here is an industrial example at Safran. As part of the development of increasingly high-performance aircraft actuators, Safran Landing Systems (SLS) must ensure the integrity of its systems during commissioning. With this…
How ArianeGroup improves simulation credibility with EikoTwin and DIC
Simulation credibility is a key aspect of the Virtual Testing concept. As the European leader in space launchers, Ariane Group participates with EikoSim in multiple Research and Development projects, including a RAPID R&D project (“MUTATION”) funded by the Direction Générale de l’Armement. This project aims at developing an industrial platform for test-simulation dialogue to meet…
Mechanical regularization in EikoTwin DIC
In EikoTwin DIC, the measurement of displacement fields is performed on the simulation mesh. However, as this mathematical problem is by nature ill-posed, a mechanical regularization parameter allows the user to add mechanical conditions to the field measurements. Contrary to most digital image correlation software, at EikoSim, we have chosen to use a mechanical “filter”….
Digital image correlation for crack measurement
In the context of crack propagation tests on composite material, EikoTwin image correlation solutions were used to meet a customer’s need. A post-processing script, exploiting the measurement data from EikoTwin DIC, was developed by EikoSim to bring satisfaction to the customer with a tailor-made solution. This work is part of Paul Nicolino’s engineering internship at…
Digital image correlation for automotive structures
Context In the context of monitoring large-scale production of 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 Figure 1). Loading tests on…
