Crack field analysis by optical DIC of short cracks in Zircaloy-4

Autor: Su, X, Wan, W, Dunne, FPE, Marrow, TJ

Publikováno v: Procedia Structural Integrity. 39:663-670

The prediction of fatigue life is most difficult for short cracks, as their local conditions may differ from what is predicted using the remote applied loading and crack geometry. Digital image correlation (DIC) can be utilized to analyze images from

Publikováno v: Advanced materials (Deerfield Beach, Fla.). 34(28)

Despite being one of the most promising candidates for grid-level energy storage, practical aqueous zinc batteries are limited by dendrite formation, which leads to significantly compromised safety and cycling performance. In this study, by using sin

Publikováno v: Tonge, S M, Simpson, C A, Reinhard, C, Connolley, T, Sherry, A H, Marrow, T J & Mostafavi, M 2020, ' Unifying the Effects of in and out-of-plane constraint on the fracture of ductile materials ', Journal of the Mechanics and Physics of Solids, vol. 141, 103956 . https://doi.org/10.1016/j.jmps.2020.103956

Effects of plastic constraint on the fracture of materials have been studied extensively. Often in such studies, the plastic constraint is divided into in-plane and out-of-plane directions and each treated separately. Such a separation adds considera
