Patterns found at driven interfaces add richness and beauty to the visual world, but they
build processing-history-dependent inhomogeneities into samples of materials whose …

Plant root system development is highly modulated by the physical properties of the soil and
especially by its mechanical resistance to penetration. The interplay between the …

Presenting current knowledge in the field of mudflows, this book includes both rheological
mudflow aspects, and information on mudflow characteristics in open channels. It includes …

Adhesively bonded elastic layers with thicknesses that are small relative to their lateral
dimensions are used in a wide variety of applications. The mechanical response of the …

Pattern-forming processes in simple fluids and suspensions have been studied extensively,
and the basic displacement structures, similar to viscous fingers and fractals in capillary …

Abstract We study the Saffman-Taylor or viscous fingering instability in yield stress fluids.
The theory for yield stress fluids shows that the dispersion equation of the instability is …

We study the viscous fingering or Saffman–Taylor instability in two different dilute or semi-
dilute polymer solutions. The different solutions exhibit only one non-Newtonian property, in …

We study the Saffman–Taylor instability in a rectangular Hele-Shaw cell. The driven fluid is a
dilute (or semidilute) polymer solution, with a viscosity that exhibits shear thinning. Other non …

Adhesion-induced instability has been observed at the interface of a flexible plate and a thin
elastic film bonded to a rigid substrate. The surface of the confined film develops undulations …

Fractal structures appear in a vast range of physical systems. A literature survey including all
experimental papers on fractals which appeared in the six Physical Review journals (A–E …
