Mechanical testing using digital speckle photography
2000 (English)Conference paper, Meeting abstract (Refereed)
Some recent applications of stereoscopic and two-dimensional digital speckle photography in experimental mechanics are presented. The examples include uses of both laser speckles and white light speckles. Topics covered are: control of the flow front when manufacturing fibre reinforced polymer composites by a closed molding process, measurement of internal deformations at high strain rates, and in opaque specimens, using flashed x-ray radiation. It is also shown how defocused laser speckles can be used to measure in-plane strain fields without the need of numerical differentiation and how laser speckles can be used to monitor the extent of the plastic zone in materials.
