0400 | DIC Digital Image Correlation non-contact 3D deformation sensor Based on a digital image correlation technique and the stereoscopic principle of the setup with two cameras objects contour, displacement and strain is measured, contactless and full field. Material and stability tests, determination of material parameters, component tests, usage n tension test machines, validation of FEM calculations, exploration of cracks, measurements at airplane components (A380, static and dynamic), dynamic tests like crash tests, pedestrian safety tests and airbag cover optimization. - Measurement fields from 1 xl mm2 to 1 Oxl 0m2 - Systems with high resolution and high speed cameras. - Multi camera systems for for thickness measurements of anisotropic materials during tensile tests, for component tests of complex shaped objects and for 360° measurements Clear and comprehensive The measurement results give meaningful informations at a glance. The color coded strain distributions show areas with inhomogenous strain. Local extreme values can be recognized instantly.One measurement corresponds to many thousand "virtual strain gauges". The visualization are similar to results of a finite element analysis (FEA). More than colorful - You can rely on it! For every measurement point and and for every measured variable (coordinate, displacement, strain) the measurement accuracy (standard deviation) is given. The reliability of the measurement are guaranteed as measurements with poor accuracy can be excluded from the results and from the interpretation. Easy to use and flexible The automatic system calibration is guaranteed finished within max. 20 seconds! One button launches the integrated analysis modules that can determine a many material parameters (Young's modulus, Poisson's number, etc.). The analysis modules can be customized from the user or from LIMESS to achieve individual calculations and visualizations.

Application example from industry and research Material tests for the determination of material parameters like Young’s modulus, poisson's ratio, etc. Component tests: strength test, Tests in load frames, test stands, temperature chamber, tensile test machine Validation of FEA simulations, crack propagation, crack growth, delamination tests, fracture analysis Dynamics tests: crashtests, pedestrian safety tests, airbag tests, dynamic tensile tests, vibration analysis, fatigue tests, stress rupture test Measurement of CTE (thermal expansion coefficient, etc.)
