Detection monitoring of a crack : DIC, a choice tool

By Team Eikosim | 19 December 2019

Context Some structures have a long service life from commissioning to replacement. These structures, when they have a fundamental role, must be able to maintain their physical integrity throughout their service life. To do this, it is essential to ensure their reliability over time. In the case of such structures as metal water pipes, different…

Digital Image Correlation for lattice structures

By Team Eikosim | 2 December 2019

Application of digital image correlation to tests on lattice structure obtained by additive manufacturing 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 constituent patterns.…

DIC for production monitoring – a collaboration with Renault and CETIM

By Team Eikosim | 4 November 2019

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…

How to validate your mechanical test?

By Team Eikosim | 15 July 2019

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 exactly…

Digital Image Correlation : test your software’s efficiency

By Team Eikosim | 11 July 2019

The quality of displacement fields measurements using Digital Image Correlation (DIC) depends on many factors which can be: Internal to the software (implementation of the algorithm, shape functions used for describing displacements, image interpolation method…); External to the software (quality of the speckle pattern, resolution of cameras, quality of calibration, …) In order to validate…

Toward quantitative image analysis of Bird strike tests

By Team Eikosim | 30 April 2019

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…
