Adjustment and validation of simulations Simulation is crucial in the development, approval, and certification of industrial products and services. It is the foundation for strategic business decisions and projects, making experimental testing even more significant. Testing and output of measured results used to be a mere requirement for compliance demonstration, but now it serves as…

By Pierre Baudoin, R&D engineer of EikoSim Blender as a supporting tool for 3D DIC tests Have you ever heard of Blender to preview a mechanical test? 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…

In today’s rapidly advancing technological landscape, the concept of the digital twin has emerged as a groundbreaking innovation with the potential to revolutionize various industries. By seamlessly integrating the virtual and physical worlds, digital twins enable businesses to gain valuable insights, optimize processes, and make informed decisions. In this article, we will explore the definition…

We have already seen together the principles of digital image correlation and the contributions of such measures. Today we will see how to choose its acquisition hardware so that it is adapted to the different use cases encountered. Image acquisition equipment means the cameras of course, but also the lenses, the lights, the mounting brackets…

Why a “global” method? Digital image correlation consists in measuring a displacement field between a reference configuration and a deformed configuration. There are two large families of algorithms to make this measurement: In the general case, the displacement field u(x) can be decomposed as a sum of functions of form Nm : where vα,m are…
