- Abstract
Abstract: The present work focuses on an experimental analysis of different photoelastic extraction methods. An adapted test rig designed in order to evaluate several extraction methods, which come from the literature and 2 new proposed methods. Their comparisons point out dissimilar behaviours between them in an experimental environment. However, some specific cases require the use of most appropriate techniques to minimise the defects influence. Therefore, a specific application of the photoelasticity is presented to illustrate the meaning of the technique used. It mainly focuses on the determination of the residual stresses and their orientation inside photovoltaic crystal silicon wafers.
