Analysis and comparison of different methods used to extract isoclinic and isochromatic parameters. Application to the determination of the residual stresses inside crystal silicon wafers
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 … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
