The IMETRUM Video Gauge measures strain and displacement on materials, components and structures.

It is a non-contact, video based instrument with applications in material testing, component testing and structural monitoring.

The Video Gauge is frequently used to overcome challenging measurement problems such as high temperature or high-speed material testing.

For straightforward tasks such as batch testing of material properties it offers significant time and cost savings over traditional methods.

Case Study

Measuring the shear component in three point bend testing of composite beams

The problem

The beams were made by embedding carbon fibre composite rods in a soft, polyurethane elastomer, matrix. The aim was to produce a beam that was very compliant against twisting but very stiff in bending and tension. Beams with those properties could be used in helicopter rotor hubs. In order to understand how the samples deformed it was necessary to measure the shear deformation at the ends of the beam, as well as the overall bending of the beam.
