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 as 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…

Read MoreHow 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…
Read MoreFE simulation correlation: a dedicated platform
As an engineer, correlation of and FE simulation often requires lots of data management within Excel or with in-house python scripts. 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…
Read MoreSimulation correlation with Abaqus: how far we’ve come in linking a solver to our software environment
Need to perform correlation between an Abaqus simulation model and measurements automatically? Whether it is by developing a python script, actually using the C++ API or developing our parsers, we have experimented a lot with reading and writing formats related to this solver, whether it is to correlate displacement or deformation fields, or simply strain…
Read MoreMechanical regularization in EikoTwin DIC
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 EikoSim we have chosen to use…
Read MoreDigital 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 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…

Read MoreSimulation validation in Excel, it’s over!
By Florent Mathieu, Ceo of EikoSim Ever wondered why you have to perform simulation validation of strain gauges in Excel ? In order to build more confidence in more refined simulation models, simulation models have to be backed up by a lot more real-world data, in order to avoid large design margins: teams now have…
Read MoreEIKOSIM BRIDGES THE GAP BETWEEN TESTS AND SIMULATIONS
By Elisa Perozzi, Strategic & Digital Marketing Manager at EikoSim EikoSim is committed to reducing the gap between tests and simulation, by developing and transmitting to its customers the use of innovative tools for the validation of their numerical simulations. Thanks to its expertise and its close link with the LMT research laboratory (ENS Paris-Saclay), EikoSim…
