First, the analytical mode I stress, the displacement fields around the tip of the SENT specimen and the concept of SIF are explained. Then, the experimental setup for DIC method is performed and different loading speeds are considered over these specimens. Furthermore, the DIC method is employed to determine the experimental displacement fields around crack tips. Finally, the experimental displacement fields obtained through the DIC method and the analytical ones are leading to identify the same SIF. © 2020 The Authors. Published by ELSEVIER B.V.
