Lucideon, the international materials technology company, has published a new white paper, ‘Digital Image Correlation for Construction’.
The paper discusses the current and potential applications of Digital Image Correlation (DIC) technology in construction and the advantages that DIC offers over conventional material, product and structural testing methods.
DIC is a digital imaging technique that is used to produce a visual 3D strain map to highlight the points of greatest strain when an object is placed under stress. The technique utilizes high resolution digital cameras that can be applied to all areas of construction, from individual building materials and products, through to large-scale structures.
Lucideon provides a dedicated DIC-based service, 3DStrain, which is capable of measuring the strains and stresses on materials and products, even those with complex geometries, and is supported by full analytical data interpretation from their experts.
Steve Newman, Senior Product Manager at Lucideon, commented:
“DIC is a powerful technique for the construction industry due to the high value data it outputs and its ability to measure both small and large-scale objects and structures. The displacement maps created and captured during tests can also be converted into video footage for greater analysis.
“Testing structures under stress is often a costly and time-consuming process, as is the testing of existing structures in situ. In these situations, DIC has the advantage of being a non-contacting and non-destructive technique, thus enabling testing without damage. This can prove to be an invaluable tool when monitoring or testing existing structures which are still fully operational.
“When a product or structure is required to be tested to failure, the high resolution cameras capture the surface strain and eventually crack propagations, displaying clearly where and when the damage begins in detail; these are usually too small to be seen by the naked eye.”
