What is an Isotropic Material? Some materials have the same properties no matter which way you measure them. These are called isotropic materials. The name comes from Greek words. Isos means equal, and tropos means way. So, isotropic materials are equal in every way you test them. Examples ...
As accepted in the literature, arterial tissues have in principle anisotropic material properties. Although some very special situations in arteries exist where isotropic constitutive models may approximate the real material behavior with sufficient accuracy, the larger part of analyses requires an ...
6 Isotropic vs. anisotropic material properties The anisotropic materials having physical properties are directional, which implies that the materials having physical response directly depend on the path in which it works [98]. The mechanical properties of anisotropic materials are different in each direc...
Moreover, the observed anisotropy was conserved among diverse cell types from several species, suggesting that the nucleus should be treated as an anisotropic, not isotropic, material. Therefore, future studies will focus on examining how key proteins (post-translational modifiers to histone tails51)...
which allows readily accessed isotropic particles to be used as seeds. In the system we describe, the MORPH process is highly controlled, reproducibly giving wormlike nanoparticles with well-defined dimensions determined simply by the amount of added complementary copolymer. The growing particles retain...
For isotropic conditions, it takes the value of the material parameter β(q=0)=β0 (Fig. 1). Fig. 1 Yield surface and bounding surface of the extended ISA plasticity for clays (d=2 has been used). Example when the intergranular strain is fully mobilized h=hb and c=cb Full size ...
such as hybrid methods and so-called global/local techniques. The extension of finite elements that were originally developed for isotropic one layered structures to multilayerd plates and shells are first discussed. Works based on classical and refined theories as well as on equivalent single layer...

Generally, two ways to introduce a defect in CLCs have been proposed (and discussed in more detail below): either by replacing a thin layer of the CLC with an isotropic material [10], or by introducing a phase jump in the cholesteric helix [7]. In the first case, in analogy with ...
