How moving cracks in brittle solids choose their path
Lital Rozen-Levy, John M. Kolinski, Gil Cohen +1
While we fundamentally understand the dynamics of 'simple' cracks propagating in brittle solids within perfect (homogeneous) materials, we do not understand how paths of moving cra…
Dynamic fields at the tip of sub-Rayleigh and supershear frictional rupture fronts
Ilya Svetlizky, Gabriele Albertini, Gil Cohen +2
The onset of frictional motion at the interface between two distinct bodies in contact is characterized by the propagation of dynamic rupture fronts. We combine friction experiment…
Topological defects govern crack front motion and facet formation on broken surfaces
Itamar Kolvin, Gil Cohen, Jay Fineberg
Patterns on broken surfaces are well-known from everyday experience, but surprisingly, how and why they form are very much open questions. Well-defined facets are commonly observed…
Crack front dynamics: the interplay of singular geometry and crack instabilities
Itamar Kolvin, Gil Cohen, Jay Fineberg
When fast cracks become unstable to microscopic branching (micro-branching), fracture no longer occurs in an effective 2D medium. We follow in-plane crack front dynamics via real-t…
Crack-Like Processes Governing the Onset of Frictional Slip
Shmuel M. Rubinstein, Meni Shay, Gil Cohen +1
We perform real-time measurements of the net contact area between two blocks of like material at the onset of frictional slip. We show that the process of interface detachment, whi…
Crack Front Waves and the dynamics of a rapidly moving crack
E. Sharon, G. Cohen, J. Fineberg
Crack front waves are localized waves that propagate along the leading edge of a crack. They are generated by the interaction of a crack with a localized material inhomogeneity. We…
