Compact anisotropic models in general relativity by gravitational decoupling
European Physical Journal C: Particles and Fields, 2018 Durgapal’s fifth isotropic solution describing spherically symmetric and static matter distribution is extended to an anisotropic scenario. To do so we employ the gravitational decoupling through the minimal geometric deformation scheme.

Kinetic helicity and MHD turbulence [PDF]
, 2000 The issue of dynamical anisotropy in helical three-dimensional magnetohydrodynamic turbulence with a mean magnetic field B₀ is investigated. Using high-resolution direct numerical simulations, we follow the evolution of various isotropic initial states ...

Minimal Geometric Deformation: the inverse problem
European Physical Journal C: Particles and Fields, 2018 In this paper we show that any static and spherically symmetric anisotropic solution of the Einstein field equations can be thought as a system sourced by certain deformed isotropic system in the context of Minimal Geometric Deformation-decoupling ...

Application of quasi-homogeneous anisotropic laminates in grid-stiffened panel design [PDF]
, 2012 Composite laminates are derived for standard configurations with quasi-homogeneous anisotropic properties, whereby in-plane and out-of-plane stiffness properties are concomitant.

Instability zones for isotropic and anisotropic multibladed rotor configurations [PDF]
Mechanism and Machine Theory, 2011 Helicopter ground resonance is an unstable dynamic phenomenon which can lead to the total destruction of the aircraft during take-off or landing phases. The earliest research in this domain was carried out by Coleman and Feingold during the decade of 60s.

Anisotropic Effects in Geometrically Isotropic Lattices [PDF]
Journal of Applied Physics, 1958 For spacings and element dimensions small with respect to wavelength the directric constant of a completely general lattice of identical elements may be represented by a tensor (ke). In many applications of artificial dielectrics it is important that the dielectric act as an isotropic medium for microwaves.

Isotropic and anisotropic bouncing cosmologies in Palatini gravity [PDF]
Physical Review D, 2010 We study isotropic and anisotropic (Bianchi I) cosmologies in Palatini $f(R)$ and $f(R,R_{μν}R^{μν})$ theories of gravity and consider the existence of non-singular bouncing solutions in the early universe. We find that all $f(R)$ models with isotropic bouncing solutions develop shear singularities in the anisotropic case.
