Rayleigh-Taylor Instability in Elastoplastic Solids: A Local Catastrophic Process.
We show that the Rayleigh-Taylor instability in elastoplastic solids takes the form of local perturbations penetrating the material independently of the interface size, in contrast with the theory for simple elastic materials. Then, even just beyond the stable domain, the instability abruptly develops as bursts rapidly moving through the other medium. We show that this is due to the resistance ...
متن کاملInhibition of Rayleigh-Plateau instability on a unidirectionally patterned substrate.
A fundamental process of surface energy minimization is the decay of a wire into separate droplets initiated by the Rayleigh-Plateau instability. Here we study the linear stability of a wire deposited on a unidirectionally patterned substrate with the wire being aligned with the pattern. We show that the wire is stable when a criterion that involves its width and the local geometry of the subst...
متن کاملSlow growth of the Rayleigh-Plateau instability in aqueous two phase systems.
This paper studies the Rayleigh-Plateau instability for co-flowing immiscible aqueous polymer solutions in a microfluidic channel. Careful vibration-free experiments with controlled actuation of the flow allowed direct measurement of the growth rate of this instability. Experiments for the well-known aqueous two phase system (ATPS, or aqueous biphasic systems) of dextran and polyethylene glycol...
متن کاملThe LAPLAS experiment: Rayleigh – Taylor instability in elastic solids
LAPLAS (Laboratory of Planetary Sciences) experiment [1] is one of the most interesting experimental schemes proposed for the study of equation of state and transport properties of high energy density matter in the framework of the FAIR (Facility for Antiproton and Ion Research) project [2]. This experiment involves a cylindrical implosion of a thick shell of Au or Pb driven by a heavy ion beam...
متن کاملElectro-elastocapillary Rayleigh-plateau instability in dielectric elastomer films.
We demonstrate, using both finite element simulations and a linear stability analysis, the emergence of an electro-elastocapillary Rayleigh-plateau instability in dielectric elastomer (DE) films under 2D, plane strain conditions. When subject to an electric field, the DEs exhibit a buckling instability for small elastocapillary numbers. For larger elastocapillary numbers, the DEs instead exhibi...
