WebFeb 1, 2024 · At a 6.5% strain, the incipient crack begins to open ( Fig. 3 b). Note that the crack onset strain depends on the strain rate [18]. This dependence is explained by the inertia of the accommodation processes governing the onset of plasticity and fracture in a loaded material. WebHIC is defined as cracking in low-to medium-strength steels where cracking is driven by the precipitation of gaseous hydrogen molecules within the crack, which typically occurs in sour (H 2 S containing) environments.

WebIncipient crack definition based on common meanings and most popular ways to define words related to incipient crack. WebCracking or pyrolysis, as it is otherwise known, is a complex phenomenon involving many reactions, intermediate species, and final products. In its most basic form it may be thought of dehydrogenation and C–C bond rupture. The reactions are highly endothermic and heat is needed to initiate and sustain them.
