How to make a speckle pattern suitable for Digital Image Correlation?
Context: Speckle patterns & digital image correlation The principle of image correlation is based on tracking information from a so-called “reference” image in the following images, often called “deformed images.” When using digital image correlation (DIC), speckle patterns are created on the surface of a specimen to address uniqueness concerns. As a result, the accuracy…
Read MoreIntegrating multi-camera DIC at MBDA
As part of its increasing competence in cutting-edge measurement techniques, MBDA has launched a process of testing and internal auditing of measurement resources by multi-camera DIC (Digital Image Correlation). After testing these measurement tools on coupon-type test campaigns, a new stage has been launched with the testing of this technology on more complex structures using multi-camera systems. Compressive…
Read MoreCrash-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…

Read MoreDigital 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…

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 finite element 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 at developing an industrial…
Read MoreSimulation correlation with Abaqus: how far we’ve come in linking a solver to our software environment
Need to perform a 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…
Read MoreMechanical 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”.…
