A High-speed Testing Machine is available for the determination of mechanical material properties as well as for the investigation of structural components and their failure behaviour. Loading of a material or a structural component can be realised up to 500,000 times faster compared to quasi-static loading in a standard test machine.

Measured quantities such as force, displacement or strain signals from strain gauges can be recorded using fast transient recorders. High-speed cameras can be combined with digital 2D or 3D image correlation for optical deformation analysis.

Depending on the fixture and test device, test articles can be tested under tension, compression, shear or bend loading.

The tests enable the determination of simulation input data and the validation of transient dynamic simulations. Also, structural components can be tested under crash relevant loading rates to investigate design approaches or crash absorber concepts.

Digital High-Speed Video Camera

The institute has several high-speed cameras. The usual frame rates range from 50 frames per second (fps) for quasi-static testing up to 240,000 fps in high-speed crash tests. Selected measurement signals can be recorded simultaneously by very fast transient recorders (1 GHz) and displayed synchronously.

Optical Deformation Analysis

Optical Deformation Analysis Optical deformation analysis using digital image correlation allows non-contact measurements of strains and displacements both in 2D and 3D.
