ARAMIS 3D Digital Image Correlation (3D-DIC) offers non-contact strain measurements that can not only replace traditional extensometers, but provide full-field strain results that are invaluable for materials research. The ARAMIS software automatically processes the image data to calculate accurate materials properties.
The ARAMIS system uses a stereo pair of cameras and powerful tracking algorithms to dynamically measure the entire surface strain map of the component tested perfect for crack detection. This data can then be processed, allowing you to choose locations of virtual strain gages and measure the dynamic behavior of individual cracks. Our software also allows engineers to return to a previous test data set and add new measurements without having to set-up and run a new test. The visualization of major strain highlights the crack propagation. This can then be used by CAE engineers for model validation.
Structural Health Monitoring
ARAMIS, TRITOP, and RVAT are optical measurements systems commonly used for Structural Health Monitoring. By taking measurements of a structure at one period of time then remeasuring at a later date, structural engineers are able to visualize displacements and strain concentration on the component’s surface providing excellent structural health monitoring of those structures. This data gives new insights into where and when the structure is starting to fail, allowing problems to be addressed before they come to fruition. This capability is an invaluable tool to civil engineers for safety testing of any structure.
Large structures testing
ARAMIS is an optical measurement system; therefore, the scale of the measuring area can be increased to cover large components. The ARAMIS software can track fiducial markers or speckle pattern to get 3D displacement and/or strain data, equivalent to thousands of LVDTs or strain gages. Our ARAMIS XL module automates the calibration process for such large fields of view. This simplifies the process of measuring components like bridges, wind turbines, and civil structures.
