Interfacial crack arrest in sandwich beams subjected to fatigue loading conditions
Abstract
A novel crack arresting device is implemented in sandwich beams tested using the Sandwich Tear Test (STT) method. In the research presented in this paper, fatigue loading was applied to the specimens to propagate the crack and determine the effect of the crack stopper. Digital image correlation was used through the duration of the fatigue experiment to track the strain evolution as the crack tip advances. Strains were related to crack tip propagation and post arrest re-initiation of the crack. Furthermore, a finite element model was used to calculate the energy release rate, mode mixity and simulate crack propagation and arrest of the crack under fatigue loading conditions. The experimental study has demonstrated that the crack stopper device is capable of deflecting and arresting propagating face/core interface cracks under fatigue conditions, and the ability to predict this behavior using numerical tools has been demonstrated.
