Fracture modeling of a weld damaged by hydrogen embrittlement
Original language description
This article presents three different models of damage and fracture of a weld that is exposed to the influence ofhydrogen embrittlement and at the same time periodically loaded. These are therefore models that must combine theeffect of hydrogen embrittlement itself as well as fatigue fracture. The first of the presented models works with asubsurface crack that was formed on an inclusion around which hydrogen accumulated, the pressure of which causeda decrease in the necessary stress intensity K at the crack front, as a result of which there will be a decrease in servicelife. The second model works with COD and last model is a variation of an approach already proposed in the literature.At the end of the work, the effectiveness of individual approaches is briefly evaluated.
