VEM Software

Tinius Olsen’s VEM range of video extensometers are a combination of precision hardware; camera, lens technology – and software; data acquisition, signal processing and data interpretation. The VEM software is the user interface through which the power of the video extensometer system is fully realised.

The software can be used for standard routine and repetitive materials testing in tension, compression, shear or flexural modes with one or two gauge length references (Lo), or for more complex testing. This may require multiple gauge length references (Lo’s) deriving multiple live strain readings and results in support of dual strain averaging, shear strain values, r&n, Poisson’s ratio and live in-test specimen alignment monitoring.

The software can be configured to operate as required for the specific task as an integral part of Tinius Olsen’s Horizon materials testing platform. It combines with a Tinius Olsen testing machine frame, capturing data and using that data in strain rate control of the testing machine. It can also be used with older Tinius Olsen and non-Tinius Olsen testing machine frames, where intimate digital integration is not always possible. Here, the strain data captured can be shared real time with the testing machine system.

It can also bring the testing machine force data signal into the software to enable graphing and results to be calculated within the software alongside the legacy testing machine user interface.

Four Levels of Software

The software is available in four levels; Horizon based, Basic, Standard and Advanced. Horizon based is the leanest in function – straight forward non-contacting extensometery, enabling real time graphs and results for strain measurement relative to basic gauge lengths.

Basic, Standard and Advanced all take advantage of the video capability, providing a post-test play back function. The recorded test, with embedded strain data, can be replayed, graphs and results reviewed. This can be a permanent record of the test stored as part of the test records alongside the traditional 2D X/Y graph and results.

Advanced is uniquely supplied with a full post-test analysis function. In addition to replaying a test for review, new measurements and gauge lengths can be applied.Original gauge lengths can be moved and replaced on the specimen – perhaps over an unexpected specimen break point. The test can then be rerun in the virtual environment  and results and graphs recalculated. This is a powerful function for those engaged in research, who may find they need more results and data after the original test.
