]. The deformation and stress fields around a cylindrical void in a single FCC crystal under plane strain condition were derived by using slip line theory[14]. Void growth and coalescence in FCC single... Results and discussion 3.1 Void growth in single crystals If the orientations of grain 1 and grain 2 are just the same, the unit cell in Fig.1 can represent a single crystal. Figs.2-3 show......
