DEFORMATION ANALYSISFullfield Measurement of deformation and strain with Q400 DIC system. |
Impact-Test / Bird strikeThe mechanical properties of components and structures can be improved by spatial resolved and contact less 3D deformation and strain measurement: The video shows an impact test on a helicopter window measured with a Q400 3D-DIC system and two Photron high speed cameras.The Q499 system is also used for bird strike tests. |
MandibleMeasurement of the strain distribution on a mandible at pressure load. In the back area (left in the color overlay) of the mandible is tension strain (red) and compression strain (blue). This reflects bending load of this mandible area. |

FemurQ400 measures the strain distribution on a femur at compression loaded. |
![]() |
Helicopter Window FrameStrain distribution of a helicopter window frame during complex loading. The color overlay shows the area of maximal shear strain. |
CFRP Bicycle FrameDeformation measurement of a bicycle frame made of CFRP (carbon fibre reinforced polymer). The shown vectors are scaled by factor 20. |

Load Test of a Stone Arch BridgeThe deflection of a stone arch bridge at a loading test is measured with Q400.The bridge span is 14m. The natural stone pattern is used for the correlation. The images shows the deflection as grid with 100x amplification. More informations in the application report. |

Road deformationGranite slabs, that are used as road pavement are moving at heavy load as single pivoted labs. The shear load at the edges can damage the slabs. |
Disc springFull field strain measurement on a disc spring (clutch) at compression load. |
![]() |
Wind tunnelMeasurement of the car body deformation in a wind tunnel up to 120km/h. The out-of-plane displacement is measured depending on the velocity. |
![]() |
Tie RodLongitudinal strain of a composite tie rod at dynamic tension and compression load. |

Rotor bladeThe 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 testThe 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). |
