How ARAMIS stacks up against strain gauges

When ARAMIS Can Replace Strain Gauges

• In material testing, providing thousands of data points
• In product design, where strain and displacement data are used to validate simulations
• In component and assembly testing, where strain gauges would be used, but the location of strain concentration is uncertain
• In structural testing to measure the continuous strain map on the surface of components
• In fracture mechanics when the location of cracks and strain gradient is unknown
• In composite or additive manufacturing where the impact of the production process on the strain distribution needs to be characterized

When Strain Gauges are Still the More Adequate Tool

• When there is no access to ARAMIS cameras to capture the surface of the component
• Infield measurements, where long term continuous monitoring is required

How to Implement ARAMIS as a Replacement to Strain Gauges

Our customers often calculate that ARAMIS is 10 times cheaper than using strain gauges in a test lab and a 100:1 improvement in the quantity of valuable data a test can provide. This is due to the fact that ARAMIS has a single initial investment cost and can be reused for any mechanical testing done in the lab where strain gauges or displacement sensors would normally be used.

Our systems are all turnkey and provided with on-site training to develop the knowledge of the test team on non-contact measuring methods. Two to three days of hands-on training is typically required to fully switch from traditional surface sensor measurements to Digital Image Correlation. Trilion Quality Systems also offers consulting services and application development to help labs implement this technology efficiently.
