EikoTwin DIC

EikoTwin DIC is a digital image correlation (DIC) software program and system that links measurements and numerical simulations.

It uses a patented Digital Image Correlation technology to provide automatic test-simulation comparison.

It allows the efficient determination of model errors and the identification and resolution of error sources. EikoTwin is the only global FE-based digital image correlation software package built with simulation validation in mind.

Testimonials

« EikoTwin DIC is a key tool in our path to make simulation validation easier and accelerate developments while limiting risks. We want the design office and the test lab to speak the same language »

Nicolas Swiergiel

Photomechanics expert

« Importing the measurement results from EikoTwin DIC into Hyperworks was straightforward and easy. This allowed us to make our simulation more predictive very quickly and to determine the correct data set. »

Julien Tersac

CAE Engineer

« This allows us to be much more confident in the validation of our technologies and will lead us to propose a mature solution to our customers more quickly. »

Benjamin Lacombe

Mechanical Design Engineer

« EikoTwin DIC helps us to increase our understanding of material testing and structural testing. It allows for accelerating development and validation process of our solutions. »

Vincent Vilamosa

System engineer

"The EikoTwin field measurement solutions have provided us with abundant data, which we can use directly in our simulation references, thanks to the fact that they take into account our needs in terms of file formats.

In addition, we are working on recalibrating our simulations with respect to experimental data, considerably enriched by the use of digital image correlation, which reinforces our confidence in using these models for our structural analyses and designs."

Applications and tutorials

Modal analysis validation – in practice

In a recent post, we mentioned how DIC can be used for modal analysis validation by comparing the measured field with a finite element simulation. A practical exercise was proposed to us by INTES: how to export results to a simulation pre-post, in this case that of the PERMAS software? In this case, we have…

Ensuring the credibility of simulation models is a concern in all fields of engineering. In aerospace engineering, structural qualification is a crucial step in ensuring that critical components are capable of withstanding the most severe operational conditions. This process is essential to ensure the safety and reliability of systems during missions. This article focuses on…

Modal analysis is a key technique used in engineering to understand the vibratory behavior of mechanical structures. It enables us to determine the natural frequencies and modal shapes of a structure, which are crucial in ensuring that it does not resonate dangerously under specific operating conditions. Traditionally, this analysis has relied on the use of…

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…

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…

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…
