Digital image correlation for automotive structures

By Team Eikosim | 8 October 2021

By Floriane Soulas, R&D Engineer at EikoSim Context In the context of monitoring large-scale production 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…

Detection monitoring of cracks with Digital Image Correlation: a choice tool

By Team Eikosim | 19 December 2019

By Floriane Soulas, R&D engineer at EikoSim 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…

Validation of a mechanical test – a collaboration with MCE-5 DEVELOPMENT and MECATEST

By Team Eikosim | 15 July 2019

By Philippe Brammer, R&D engineer at EikoSim 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…

Toward quantitative image analysis of Bird strike tests

By Team Eikosim | 30 April 2019

By Florent Mathieu, Ceo of EikoSim 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…

Towards a better understanding of mechanicals tests thanks to DIC, with ALSTOM and CETIM

By Team Eikosim | 17 September 2018

Consistency of simulation and test data The consistency of test data and numerical results is paramount while carrying out the simulation-experiment comparison required to validate numerical simulations. First of all, mechanical tests need to respect the specifications laid out during their design: sample geometry, load path, location and orientation of the loading point, measurement points…
