Abstract
Kinking is a deformation mechanism ubiquitous to layered systems, ranging from the nanometer scale
in layered crystalline solids, to the kilometer scale in geological formations. Herein, we demonstrate its
origins in the former through multiscale experiments and atomistic simulations. When compressively
loaded parallel to their basal planes, layered crystalline solids first buckle elastically, then nucleate
atomic-scale, highly stressed ripplocation boundaries – a process driven by redistributing strain from
energetically expensive in-plane bonds to cheaper out-of-plane bonds. The consequences are far
reaching as the unique mechanical properties of layered crystalline solids are highly dependent upon
their ability to deform by kinking. Moreover, the compressive strength of numerous natural and
engineered layered systems depends upon the ease of kinking or lack there of.
