Impact-Testing

The mechanical properties of components and structures can be improved by spatial resolved and contact less 3D deformation and strain measurement: The video shows an example impact test on a transparency measured with a LIMESS Q400 3D-DIC system together with two Photron high speed cameras. The color coded strain fields shows the propagation and reflection of the stress waves after the impact of a sphere. At every surface point 3D coordinates, displacement and strain is measured with high temporal resolution. The full field measurement results give useful information for the mechanical optimization and improves quality, life time and safety of products e.g. in aerospace and automotive industry.

Helicopter Window Frame

Strain distribution of a helicopter window frame during complex loading.

The color overlay shows the area of maximal shear strain.

Rotor blade

The 3D deformation of a rotor blade is measured with Q400. The cameras are precisely synchronised to the rotation (4/sec)

The image shows the color coded out-of-plane deformation and the measurements along a polygon line.

Panel Compression test

The buckling of an aircraft panel during a compression test is measured with the Q400 system. The Q400 system gives fillfield 3D displacement on the panel surface.

The images show the test stand with panel as well as the overlay and 3D visualization of the out-of-plane deformation (=buckling).
