EikoTwin Digital Twin
The EikoTwin Digital Twin is a highly effective tool to enhance simulation model calibration accuracy.
This innovative technology relies on digital models that are specifically calibrated using test data, ensuring that the resultant simulations provide highly accurate and reliable results.
Digital twin technology implements "augmented simulations", which use the measured data as boundary conditions, but also allow simulation-enabled model calibration of material model parameters to bring the simulation closer to the expected result.

Measurement robustness and the use of “automatic meshing”: focus on synchronized calibration for DIC
Continuing our series of articles on best practices in Digital Image Correlation (DIC), today we present calibration using synchronized target images (with or without mesh alignment), a new procedure that enables the simultaneous determination of intrinsic and extrinsic camera parameters. This procedure complements the hybrid approach already available in EikoTwin DIC, which remains relevant when…
Your First DIC Experiment with EikoTwin: Setup Tips for Altair Users
As a user of the Altair Partner Alliance, you have free access to EikoTwin DIC — a powerful tool for full-field strain and displacement measurement through Digital Image Correlation (DIC). But while the software is directly accessible, many users hesitate to take the first step simply because they don’t have a dedicated experimental setup at…
Designing optimized specimens for composite materials: from normative testing to simulation-assisted identification
This article is based on the M2 internship work of Antoine Vintache in collaboration with François Hild of the Laboratoire de Mécanique de Paris-Saclay, and presented at the ECCM21 conference [1]. This work is supported by ArianeGroup. In experimental mechanics, tests on composite materials are often based on standardized specimen geometries. These geometries – uniaxial…

Crack tracking on a structure : practical use case in thermal fatigue @ Liebherr Aerospace
In the aerospace industry, where component reliability is critical, the study and tracking of cracks is of paramount importance. Liebherr Aerospace, a leading manufacturer of heat exchangers, sought EikoSim’s expertise for an in-depth study of crack development under extreme thermal fatigue loading. The study, detailed below, provides a comprehensive overview of the methods, results and…
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…
