Full-field measurement of thin plate irradiated by CW laser

A three-dimensional digital image correlation technique (3D-DIC) combined with infrared temperature measurement system is presented to investigate the thin aluminium alloy plate irradiated by CW laser for full-field measurement, which can present real-time deformation and temperature results. The influence of incidence laser power is investigated, and the result shows that the deformation and temperature of the spot center increase linearly as the incidence laser power increases. The model result agrees well with the experiment result. The three-dimensional digital image correlation technique (3D-DIC) combined with infrared temperature measurement system is a kind of effective measuring method to the analysis and understanding of the failure mechanism.
