Incipient cracking
WebMar 27, 2024 · By incipient plasticity or cracking, we refer to the inelastic deformation events occurring at the onset and during the elasto-plastic transition (e.g., pop-in). Consider a defect-free crystal, the incipient plasticity will be dominated by dislocation nucleation, with probable concurrent occurrence of dislocation multiplication and/or glide ... http://www.mem50212.com/MDME/MEMmods/MEM30007A/AssDegRE/lect03-mechanical-testing/webpages/fractured-input-shaft.html

The fracture surface of incipient crack shows a quasi-cleavage (QC) topography with secondary cracks, see Fig. 10 (b) and (c). The topography in the transition zone was ductile with micro-void coalescence (MVC) and QC. The remaining fracture topography was ductile with MVC, see Fig. 10 (d

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.
Web– Interdendritic stress corrosion cracking (IDSCC) – Low potential stress corrosion cracking (LPSCC) ° Transgranular stress corrosion cracking (TGSCC) • Criterion for EAC propagation: ♦ There is a mechanism to protect the crack sides ♦ If this is not met, then the incipient sharp crack will devolve into a blunt notch and will arrest WebSep 15, 2024 · Overheating is one of the most common causes of cracking. Extreme temperatures result in grain boundary liquation (incipient melting) associated with …
WebFatigue moves from incipient cracking to interconnected cracks and finally to spall. This occurs when cracks intersect surfaces, allowing chunks and platelets to be carried away by the lubricating fluid. Further rolling contact produces more and larger chunks and platelets.
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].
