DOI: 10.1088/1361-6501/ab461e
Abstract: The characterisation of high temperature materials for extreme environment implies experimental challenges. Displacement measurements using digital image correlation (DIC) have proven to be an efficient non-contact method even at high temperatures. This paper uses global… read more here.
