Registration Date 11-04-2025 Organization E.O. Paton Electric Welding Institute (PWI) popup.description1 The aim of this work is to design and develop a measuring method for determining the deformed state of a material during the initiation of hot cracks in the welding process by adapting modern optical and digital technologies. The research focuses on improving the digital image correlation (DIC) and Lucas-Kanade algorithms to enhance the accuracy of displacement and strain measurements, taking into account the specifics of images obtained during welding. popup.nrat_date 2025-04-11 Close
