Noncontact digital gage enables precise materials, structural testing

Trilion Quality Systems (King of Prussia, Pa., U.S.) exhibits its Aramis optical strain gage, a noncontact and material-independent measuring system that can provide critical data such as full-field optical strain, 3D displacement and vibration analysis with ease. Aramis is designed to be a cost-effective alternative for foil gages and extensometers. It can operate with 50 times less labor/time and provide 100 times more data, according to the company. With applications from finite element analysis (FEA) validation, material/structural testing, structural health monitoring and high-speed measurements, the Aramis optical strain gage can be used for a wide range of industries from automotive, aerospace, biomechanics and more.

At Aramis’ core is 3D digital image correlation (3D-DIC), a noncontact measuring technique based on advanced image processing, which can provide accuracy comparable to a mechanical gage. DIC is capable of mapping 3D coordinates and evaluating displacement and strain maps on the surface of measured samples. DIC uses a stochastic pattern and/or point markers to track the surface of the materials with subpixel accuracy or microns of motion.

In addition to its testing system, Trilion can perform its services on-site at customer facilities to provide flexibility and quick implementation or deployment of technologies.
