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.

WebThe ROSEN Group has created a Pipeline Integrity Framework for Cracking that is a consolidation of current industry best practices and the most advanced pipeline crack inspection solutions with the knowledge of subject-matter experts. It outlines all the key elements needed to develop a comprehensive and justifiable integrity management … WebFracture surface analysis showed that the scatter was due to incipient melting in the grain boundary region. The melting contributed to low fracture strain but had only a small on the incipient cracking strain. Gleeble tests, which could be interrupted by water quenching, were used to study the incipient intergranular melting of Inconel 718.
WebThe incipient cracking, due to the differential in coefficient of linear thermal expansion of the G-1O, epoxy-glass and the electrodeposited copper is eliminated by the use of a ductile layer of cyanide copper. ...

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.
