Full field deformation analysis applied to improved CTOD concept
Highly precise measuring of 3D displacements in the vicinity of the crack tip by using object grating method enables the visualization of deformation and characterization of the crack propagation process. Modified CTOD concept based on deformations analysis along the set of lines shifted in direction of the crack propagation is introduced. Through the visualization it provides comprehension of specimen's behavior in conditions of high stress concentration and large displacements. Object grating method is advantageously used to analyze two specimens with initial crack in a macroscopic heterogeneous welded joint. The crack propagates from the over-match (OM) material towards the under-match (UM) material or vice versa, when the crack propagates in the opposite direction. The results of the experiments show the potential of object grating method for acquiring deformation field around the crack tip because is enabled to observe the fracture behavior in heterogeneous material structure during the crack propagation.
