Local DIC or Global DIC: Which is the Best Method for Your Application?
Introduction Digital Image Correlation (DIC) relies on two main algorithmic families: local DIC (or subset-based) and global DIC (or FE-based). Both approaches produce displacement and strain fields, but their internal workings, strengths, and limitations can be different. First, it is important to note that in 90% of cases, the results of the two methods are…

FEA Model Validation with DIC — Bird Strike Impact Testing
In the aerospace and automotive industries, the resistance of structures to various high-speed threats is a guarantee of certifiability. In aerospace, certification for bird strike is a major issue for the safety and certification of equipment and systems. Tests are carried out not only to assess the structural integrity of materials, but also to validate…
Forming and DIC: measurement of large deformations
Experimental validation of forming processes, such as crimping, requires accurate characterization of local deformation fields, which can be achieved using DIC. A recent measurement campaign was conducted on an industrial part with severe geometric constraints, with an analysis area located on a section approximately 2 mm thick. Beyond the small size of the area of…
High-Speed DIC — Full-Field Measurement of Airbag Deployment
This article showcases a use of high-speed DIC for validating the behavior of a dashboard opening. Passenger safety is a top priority in the automotive industry. In the event of a collision, the airbag must deploy quickly and effectively to protect the vehicle’s occupants. However, this ultra-fast process is directly influenced by the structure and…
Desing of a Thermomechanical Test Bench — Coupled DIC and Infrared Imaging
This article was written in collaboration with Thibaut Archer, researcher at ONERA. Setting up thermomechanical tests in a controlled environment is a major challenge for validating numerical models in structural mechanics. Optimum design of the test rig is essential to ensure accurate acquisition of displacement and temperature fields, via DIC and IR measurements, particularly when…

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…
