Understanding ans controlling the sources of discrepancy between tests ans simulations

By Team Eikosim | 1 March 2019

Adjustment and validation of simulations Simulations play an enhanced role in the design, the qualification and the certification of industrial products by forming the basis of strategic decisions. Therefore, the role devolved to experimental testing has also been modified. These tests were the essential part of the demonstration of compliance, but now they become references…

Instrumenting structural tests with imaging techniques: what benefits?

By Team Eikosim | 17 November 2018

It is quite simple to assess the benefits of using digital image correlation. For test engineers, DIC makes it feasible to prospect a larger area, to better understand the physical phenomena at stake by using a non-intrusive measuring method. For engineers working on numerical simulations, it is now possible to validate their models using vaster…

Virtual design of experiments with Blender

By Team Eikosim | 16 November 2018

Blender as a supporting tool for 3D DIC experiments Have you ever heard of Blender? 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 based photo-realistic renders of any 3D environment. In particular, it can be used…

The digital twin: bringing the real world into your simulations

By Team Eikosim | 17 October 2018

To estimate a structure’s mechanical behavior, proactive numerical studies have become common practice in mechanical engineering. Finite element modeling is now involved at all stages of the mechanical design project, from material behavior estimation (especially for composite materials), to intermediate assemblies, all the way up to structural computations. At each of the previous stages, simulations…

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…
