Anisotropic-Isotropic Transition of Cages at the Glass Transition
Physical Review LettersCharacterizing the local structural evolution is an essential step in understanding the nature of glass transition. In this work, we probe the evolution of Voronoi cell geometry in simple glass models by simulations and colloid experiments, and find that the individual particle cages deform anisotropically in supercooled liquid and isotropically in ...

The response of isotropic turbulence to isotropic and anisotropic forcing at the large scales
Physics of Fluids A: Fluid Dynamics, 1991The nonlinear interscale couplings in a turbulent flow are studied through direct numerical simulations of the response of isotropic turbulence to isotropic and anisotropic forcing applied at the large scales. Specifically, forcing is applied to the energy-containing wave-number range for about two eddy turnover times to fully developed isotropic ...

On the formulation of isotropic and anisotropic damage
1998Considerable effort has been devoted in recent years to the formulation of degradation and damage. A large portion of the models, however, still correspond to variations of the traditional ``(1-D)-type'' scalar damage formulation, while a smaller portion represents other kinds of isotropic or anisotropic degradation.

Anisotropic Consolidation of Initially Isotropic Soil
1982It is recognized that almost all natural soil deposits show a certain amount of anisotropy that affects both the stress-strain relationships and the ultimate shear resistance [1,2].

Plastisches Verhalten isotroper und anisotroper Stoffe
2001Ein elastischer Korper ist durch die Materialgleichung $$ \sigma _{ij} = f_{ij} (\partial x_p /\partial a_q ) $$ (3.1) definiert, die im unverformten Zustand des Korpers auf den Nulltensor fuhrt. In (3.1) ist fij eine tensorwertige Funktion vom Deformationsgradienten (1.13a), fur die wegen σij; = σji auch fij = fji gelten muss. Berucksichtigt
