Delayed hydride cracking of Zr-2.5%Nb pressure tube material due to partially constrained precipitates
TL;DR: In this paper, a finite element method was used to predict the region in the matrix in which radial hydride is likely to form and fracture, by taking into consideration grain-size, texture and multi-axial state of stress.

Evaluation of effect of hydrogen on toughness of Zircaloy-2 by instrumented drop weight impact testing
TL;DR: In this article, the degradation in fracture toughness of Zircaloy-2 was evaluated by carrying out instrumented drop-weight tests on curved Charpy specimens fabricated from virgin pressure tube.
Journal ArticleDOI
A combined SIF and temperature model of delayed hydride cracking in zirconium materials
TL;DR: In this paper, an integrated model of DHC which combines two independent calculation models is presented, the first calculation sub-model is designed to predict the critical characteristics of hydrides (their length and thickness) depending on both temperature and SIF.
