| Abstract: | The plastic flow localization patterns for alkali halide LiF crystals under compression have been investigated. The main spatiotemporal
regularities of the strain localization at different stages of deformation hardening in the single crystals have been established.
The relation has been traced between the orientation of localized strain zones and the crystallography of slip systems of
the test specimens studied simultaneously by the double-exposure speckle photography and photoelasticity methods. |
