According to the triaxiality analyses, the sharp curves of void boundaries along with the edges of solder layer are the most susceptible sites for crack initiation.
High-resolution transmission electron microscopy observation revealed that the grain boundary in cubic zirconia bicrystals was clean and atomically sharp without any void or grain boundary amorphous layer.
It is for this reason that the closed-form determination of the stress field near a sharp inclusion or void is crucial for the design of ultra-resistant composites.
From the SEM images, we observed that the length of all fibers is found to be same with sharp ends having voids in each MoS2 bundles.
The negative space (the passageway between the two houses, the shadow under the extended roof off the second building) symbolizes Mrs. Ramsay's death, while the retaining wall on the right side, with its sharp edges, registers the void against something solid.
The sharp-interface description of void growth may thus be considered a generalization of the classical sharp-interface models of particle growth from a supersaturated matrix, as in solidification and precipitation.
The lack of sharp-interface models for void growth under irradiation motivated Hochrainer and El-Azab (2014; 2015) to introduce an elaborate one.
Nevertheless, it is useful to first review the classical models of precipitation since they represent limiting cases of the generalized sharp- and diffuse-interface models for void growth, before introducing the sharp interface model of voids reported in (El-Azab et al., 2014; Hochrainer & El-Azab, 2015).
The IMAGE mission identified not only conventional pictures of the plasmasphere (plasmapause, tails, and duskside bulge), but also novel structures, such as depleted regions that are called "voids" and a sharp azimuthal gradient in He+ density called the "shoulder".
Arsenal's Lukas Podolski, who had become a forgotten man in the last couple of years, has reappeared just in time, looking sharp and ready to fill the void on the left.
