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…
Read MoreBuilding simulation credibility: the validation of Ariane 6’s Dual Launch Structure
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…
Read MoreModal analysis: how can Digital Image Correlation (DIC) help?
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…

Read MoreVVUQ references & resources for solid mechanics & aerospace
By Florent Mathieu, CEO of EikoSim After several occasions where I’ve been given advice to consult specific documents in the field of validation testing and VVUQ (Verification, Validation, and Uncertainty Quantification), I’ve decided to write a blog about this. Here is a more detailed list of important papers, books or websites that I found along…
Read MoreWhat is VVUQ (Verification, Validation, and Uncertainty Quantification)?
By Florent Mathieu, CEO of EikoSim In the world of scientific simulations, ensuring accuracy, reliability, and credibility is of utmost importance. To achieve this, scientists and engineers employ a rigorous process called Verification, Validation, and Uncertainty Quantification (VVUQ). This blog article explores what VVUQ entails, its applications across various software product domains, and its role…
Read MoreDigital Image Correlation – The basics
By Florent Mathieu, CEO of EikoSim What is digital image correlation? The Digital Image Correlation (DIC) technique is a non-contact, full-field measurement approach that enables the assessment of the deformation and motion of objects. This is achieved by comparing digital images of the object before and after deformation. DIC measurement is a technique used to…
