2018, International Journal of Solids and StructuresCitation Excerpt :It's seen that, for both specimens, the fracture surfaces can be divided into three regions: the crack initiation (indicated by number “1” in Fig. 12), the crack propagation (indicated by number “2”) and the final fracture (indicated by number “3”). The crack initiation region has clear river patterns toward the initiation site at the edge of the specimen (similar patterns have been observed in (Gloanec et al., 2010)). The close up views of SEM images for the crack propagation and final fracture regions have dimple growth and coalescence characteristics of ductile fracture, which is consistent with the patterns shown in (Daly et al., 2007a).
A shakedown analysis of high cycle fatigue of shape memory alloys
2016, International Journal of FatigueCitation Excerpt :Several experimental investigations and fatigue methodologies have analyzed both SMA structural fatigue (component failure) and functional fatigue (the evolution of shape memory effect and pseudoelasticity under repeated thermo-mechanical cycles); see Robertson et al. [78] as review article. Experimental investigations are generally coupled with observations to track the nucleation and evolution of martensite and austenite during mechanically unstable regimes with the final aim of characterizing the material fatigue response on a microscopic and even macroscopic level [11,17,27,28,39,41,51,69,89,96]. Experimental observations have also inspired a series of fatigue approaches aimed to estimate the lifetime, as a macroscopic crack initiation criterion.

2013, Materials Science and Engineering: ACitation Excerpt :For each fatigue sample, several thin foils were studied to obtain large observation areas and to provide a representative point of view. The cyclic strain-stress behaviour of a TiNi shape memory alloy has already been presented elsewhere [7,12–14]. Tests were performed at 50 °C to induce the formation of the austenite phase.
