Taking place from 10th 12th March 2015 in Paris, the exhibition will be a showcase for Imetrum’s video-based, high-resolution, non-contact measurement system that has the Video Gauge™ software at its heart.
The video measurement system is used throughout industry to measure strain, displacement, rotation plus other important parameters in materials testing. Using pattern recognition and sub-pixel interpolation to measure the exact displacements of selected point in an image, it is particularly suited to the testing of composites in mission critical markets such as automotive and aerospace.
Improved usability is one of the main foci of the new Video Gauge™ V5, particularly around generating precise 3D measurements. It is now possible to use pre-calibrated camera pairs to generate measurements at the micron level within minutes of turning the system on. This has eliminated the difficult and time consuming setup process that is required with other 3D measurement systems.
For those interested in measuring shear strain, a new measurement has been introduced. The measurement allows shear strain calculation via both the traditional ±45 degree gauge approach, and also via precise measurement of change in angle. Whereas the ±45 degree approach is an approximation that is only valid for small shear strains (typically less than 1%), the change in angle approach is accurate even at large strains. The availability of both options allows the user to choose either to take measurements that are equivalent to using traditional ±45 degree bonded strain gauges or, for the first time, make measurements that are accurate even at large strains.
These major new features incorporated into V5 of Video Gauge™ software will enhance the versatility and accuracy of Imetrum’s video measurement system and gives users many time saving advantages. They also sit well alongside recently introduced features such as the multi-language platform, improved test visualisation and review, and a suite of Digital Image Correlation options.
Visitors to Imterum’s stand will also be able pick up a host of Application Notes including one that explains how the system can be used to achieve the exacting requirements of ISO527-1: 2012 ASTM D638 equivalent. The Application Note outlines the tests that were undertaken and the significant advantages of using non-contact extensometry over other methods.
