Validation of full-field techniques: discussion of experiences

Validation and calibration of optical full-field techniques that are used to measure strain and displacement in experimental mechanics is a prerequisite for validating numerical stress analyses. ICEM14 brings together practising engineers from around the world to exchange their experience regarding validation and calibration from everyday measurements with different optical techniques. The discussion addresses the following issues: (i) experience in calibrating measurement equipment based on imaging; (ii) reference measurements and calibration artefacts; (iii) validation of finite element analyses by comparison to experimental data; and (iv) uncertainties in full-field measurements.
