The characterisation of the mechanical properties of components and structures can be improved by spatially resolved and non-contact 3D deformation and strain measurement. 3D coordinates, displacement and strain are measured at each surface point with high temporal resolution. The results of the full-field measurement provide useful information for mechanical optimisation and improve the quality, durability and safety of products, e.g. in the aerospace, automotive and civil engineering industries. Currently, the Q400 is in use on our mechanical testing machine, where thin-walled textile materials are subjected to inhomogeneous loading conditions due to compression and torsion in structural tests, and full-field measurements of distortion enable the simultaneous determination of all stiffness parameters (incl. shear).
Application: Rheological properties and viscosities of paints, adhesives, suspensions, dispersions, emulsions, liquids, polymer solutions and polymer melts; static shear tests and dynamic mechanical tests; flow behaviour; deformation stability; creep behaviour, stress relaxation behaviour; thixotropy, rheopexy.
