Instability of Compacted Residual Soil
Geosciences, 2021 Static liquefaction of loose sands has been observed to initiate at stress ratios far less than the steady-state stress ratio. Different collapse surface concepts largely based on undrained triaxial test results have been proposed in the literature to ...

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 ...

Grinfeld instability on crack surfaces [PDF]
Physical Review E, 2001 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 numerically that the energy of a wavy crack becomes smaller than the energy of a straight crack if the crack length exceeds a critical length L(c)=5.18 L(G) (L(G) is the Griffith

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 ...

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 ...
