Digital Image Correlation (DIC) Testing Service
Lucideon's digital image correlation testing service can offer you vital insights and understanding into performance, durability, and failure analysis of your materials and products when interacting with external forces, weights, strains and stresses.
Our experts can perform testing and analyze the detailed data to provide you with clear, simple, quantitative results.
Digital image correlation is a non-contact optical technique for measuring motion and deformation of objects by comparing digital images of the object before and after deformation. It’s used for a wide variety of applications from characterizing material properties to identifying structural damage and quality testing in manufacturing.
The technology can:
- characterize mechanical behavior of materials or the behavior of non-homogenous and non-isotropic materials
- visualize the response of a component or structure under various loading conditions
- obtain strain maps of components under load
- verify and refine finite element analysis models of complex geometries
Digital image correlation can deliver non-destructive, full-field surface strain measurements on objects under load. We deliver movement tracking at the pixel-level on most materials, for a range of sizes on complex geometries.
With Lucideon you receive full analytical interpretation of the data from our experts, allowing you to make use of the vast, in-depth feedback quickly and easily.
Digital image correlation also produces visual results that show how strains and cracks develop and grow, up to the point of failure and offers you detailed digital imagery showing the displacement on your product, correlated against a no-load condition.
Digital image correlation testing has applications in the construction, aerospace, healthcare and nuclear sectors.
Key features include:
- quantitative results: calibrated images provide strain or displacement in three dimensions
- portable system: readily transportable and can be applied in Lucideon or client facilities, or in the field on large structures
- scalable: it can be applied to large structures such as bridges, down to filaments, fibers, and sub-scale components, including images obtained from a scanning electron microscope (SEM)
- versatile: can be applied to virtually any material of almost any geometry, under static or dynamic loads
- non-contacting and non-destructive: enables proof-testing of components without damage
Lucideon has a comprehensive quality assurance program, which is in compliance with 10CFR50 Appendix B, ISO 17025 and Nadcap (aerospace and defense industries).
These rigorous QA requirements are applied to every job we perform as standard.
