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…

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…

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…

Context: Speckle patterns & digital image correlation The principle of image correlation is based on tracking information from a so-called “reference” image in the following images, often called “deformed images.” When using digital image correlation (DIC), speckle patterns are created on the surface of a specimen to address uniqueness concerns. As a result, the accuracy…
