Surface Instabilities in Cracks [PDF]
Physical Review Letters, 1998 The surface of a propagating crack is shown to be morphologically unstable because of the nonhydrostatic stresses near the surface (Asaro-Tiller-Grinfeld instability). We find that the energy of a wavy crack becomes smaller than the energy of a straight crack if the crack length is a few times larger than the Griffith length.

Viscoelastic surface instabilities [PDF]
Comptes Rendus. Physique, 2009 We review three different types of viscoelastic surface instabilities: The Rayleigh–Plateau, the Saffman–Taylor and the Faraday instabilities. These instabilities are classical examples of hydrodynamic surface instabilities. The addition of a small amount of polymer to pure water can alter its flow behavior drastically and the type of instability may ...

Creep crack energy dissipation and instability prediction in micritic bioclastic limestone
Frontiers in Earth Science, 2023 Time-dependent deformation and long-term stability of rocks are important issues in water conservancy and geotechnical engineering. Currently, there are no well-accepted theoretical criteria with which to predict stability and damage considering time ...

Instability of certain capillary surfaces [PDF]
Manuscripta Mathematica, 1989 Previously the second author has constructed, for a uniform gravitational field, a container shape \({\mathcal C}\) such that there exists a continuum of rotational symmetric capillary surfaces which have the striking property that they all meet \({\mathcal C}\) in the same contact angle \(\gamma\), bound with \({\mathcal C}\) the same volume V of ...

Surface instabilities and nuclear multifragmentation [PDF]
Nuclear Physics A, 1992 Central heavy-ion collisions, as described by a Boltzman-Nordheim-Vlasov calculation, form nuclear disks that break up into several fragments due to surface instabilities of the Rayleigh-Taylor kind. We demonstrate that a sheet of liquid, nuclear or otherwise, stable in the limit of infinitely sharp surfaces, becomes unstable due to surface-surface ...

Surface Instability in a Nematic Elastomer
Physical Review Letters, 2023 Liquid crystal elastomers (LCEs) are soft phase-changing solids that exhibit large reversible contractions upon heating, Goldstone-like soft modes and resultant microstructural instabilities. We heat a planar LCE slab to isotropic, clamp the lower surface then cool back to nematic.
