Digital Image Correlation for lattice structures
Why use Digital Image Correlation when testing lattice structures? This is what this article is about. Interest in lattice structures is growing rapidly for the development of aeronautical and space components in particular. In addition to the significant mass gains they allow to consider, they offer the possibility of optimising their behaviour based on their…
Digital Image Correlation for production monitoring – a collaboration with Renault and CETIM
Context As part of the large-scale production monitoring of automotive parts, it is essential to ensure that the reliability of the manufactured parts remains constant throughout the part’s production cycle. In order to make sure of this, parts are regularly sampled from production lines and tested to ensure that they still meet the required safety…
Validation of a mechanical test – a collaboration with MCE-5 DEVELOPMENT and MECATEST
EikoTwin DIC to validate your test kinematics, with MCE-5 DEVELOPMENT and MECATEST The purpose of a mechanical test is to submit a part or an assembly of parts to a specific stress in order to evaluate its elementary or in-service performances. The strong hypothesis, strengthened by theory or numerical simulation, is that the test bench…
Verification of the robustness of an Image Correlation software – a collaboration with SAMWELL Testing Inc.
The quality of displacement fields measurements using digital image correlation depends on many factors which can be: In order to validate the robustness of a digital image correlation software algorithm, it is interesting to compare the results of the software with other reference measurements obtained independently but under identical test conditions (same external factors to…
Previsualization with Blender of a complex structural test
Written by Matthieu Vitse Matthieu Vitse is a freelance scientific visualization expert. He has a PhD in computational mechanics from ENS Paris-Saclay, and his main activity now focuses on the post-treatment and visualization of large complex data simulations and experiments. More info at www.sciviz.fr (from Vitse et al. Toward virtual design and optimization of a…
Toward quantitative image analysis of Bird strike tests
Redactors : N. Cordero, F. Fremy, M.Beneck for Saint-Gobain, F. Mathieu for EikoSim Aircraft radomes produced by Saint-Gobain are made of composite materials. In addition to the usual design requirements that these structures must comply with (lightness, aerodynamic shape, impact resistance), they need to be RF transparent so that the systems they shelter may function. This…
Understanding and controlling the sources of discrepancy between tests and simulations
Adjustment and validation of simulations Simulation is crucial in the development, approval, and certification of industrial products and services. It is the foundation for strategic business decisions and projects, making experimental testing even more significant. Testing and output of measured results used to be a mere requirement for compliance demonstration, but now it serves as…
How to preview your test using Blender software?
By Pierre Baudoin, R&D engineer of EikoSim Blender as a supporting tool for 3D DIC tests Have you ever heard of Blender to preview a mechanical test? Blender is a comprehensive, open-source, cross-platform 3D creation suite that can be used to create photo-realistic renders, animations, or even full-length movies. Blender’s render engine can produce physically…
The digital twin definition: bringing the real world into your simulations
In today’s rapidly advancing technological landscape, the concept of the digital twin has emerged as a groundbreaking innovation with the potential to revolutionize various industries. By seamlessly integrating the virtual and physical worlds, digital twins enable businesses to gain valuable insights, optimize processes, and make informed decisions. In this article, we will explore the definition…
Digital Image Correlation, how to choose your acquisition hardware?
We have already seen together the principles of digital image correlation and the contributions of such measures. Today we will see how to choose its acquisition hardware so that it is adapted to the different use cases encountered. Image acquisition equipment means the cameras of course, but also the lenses, the lights, the mounting brackets…
