“…Growing voids reach a critical size, relative to the spacing, and local plastic instabilities develop between voids, resulting in failure. 56 Under such conditions, and as shown in Figure 2.16, four types of fracture may be observed in the case of A356 alloy castings exposed to various temperatures for short and extended periods of time. 48 These fracture types indicate the following details:…”

“…In samples which experience large amounts of plastic deformation, cavity initiation is not determined by the magnitude of the applied stress but rather by the local state of deformation. 56 Fracture of this type occurs by means of blocked slip and pile-up mechanisms. Oj 57 As the plastic deformation and shearing continues, the voids eventually coalesce, and failure then occurs.…”

“…This formulation means that coalescence starts provided cavity growth is promoted by matrix viscoplasticity. For the "d" mechanism, no coalescence law was used, as for n = 1 the stability of the material prevents void coalescence (Ashby et al, 1979). The resulting set of model parameters is given in Section 8 of Table 5.…”

“…In the past, focus was placed on ductile fracture as one of the dominant fracture mechanisms for metals with high ductility, particularly for aluminum alloys processed at room and elevated temperatures. According to Ashby's fracture mechanism maps for FCC alloys [2], there are several fracture mechanisms operating in a range of elevated temperatures and tensile stresses (corresponding strain rates). Therefore, there is a need to address multiple fracture modes when developing criteria to characterize hot fracture behavior during thermo-mechanical processing.…”
