kink band

kink band

[′kiŋk ‚band]
(geology)
A deformation band in a single crystal or in foliated rocks in which the orientation is changed due to slipping on several parallel slip planes. Also known as joint drag; knick band; knick zone.

But it never really accurately accounted for the rippling and kink band formation observed in most layered solids.
The latter effect was labeled kinking nonlinear elasticity by Barsoum about a decade ago, because it involved the formation of kink bands permanent buckles in the layers.
The observation is significant because these are the same sort of kink bands that are ubiquitous in geologic formations and layered solids that have been deformed.
Kink band formation Is the observed compression failure mechanism in high performance polymeric fibers.
Since the kink band boundary between deformed and undeformed sites appears to be optically sharp, the calculated distance could correspond to an effective fibril length during compression failure.
A similar kink band structure can also be observed in geldrawn UHMW-PE fiber with decalin as the solvent, but the density of the bands in the fiber is much less.
In the fiber with a draw ratio of about 40, kink bands were observed.
Kink bands associated with faulting trend NNE to ENE with WNW to NNW side up.
Kink bands displaying normal motion are spatially related to faults striking N to NNE, and are overprinted by [D.
PAN based fibers typically buckle on compression and form kink bands at the innermost surface of the fiber.
the dynamic deterioration (structural deterioration) due to kink bands (ref.
Further, a morphology assumed to have grown from the kink bands was observed in a sample just before the fracture thereof.
