This new notation, with only one subscript for the stress and strain, numbered from 1...6, is helpful as it allows the equations of anisotropic elasticity to be written in matrix form.

Such materials are often unwisely referred to as anisotropic which is a term embracing the most general case in which the principal material constants vary in magnitude and direction from point to point.

To define an anisotropic material, set the Anisotropy field in the Material database to Diagonal and specify the material model parameters for each diagonal component.

Anisotropic materials, also known as “triclinic” materials, are direction-dependent media composed of unsymmetrical crystalline structures. They are characterized by edges, branches, corners and bends, and are expected to provide more high-energy sites.

Understand the relation between internal material symmetries and macroscopic anisotropy, as well as the implications on the structure of the sti ness tensor. Quantify the response of anisotropic materials to loadings aligned as well as rotated with respect to the material principal axes with emphasis on orthotropic and transversely-isotropic ...

2024年3月1日 · This paper presents a theoretical and micromechanical procedure for determining the macroscopic behavior of voided materials with anisotropic matrix constitutive behavior.

The procedure to specify anisotropic elastic material properties resembles that for nonlinear properties. You first activate a data table using the TB command (with Lab = ANEL) and then define the terms of the elastic coefficient matrix using the TBDATA command.

The constitutive equation for anisotropic materials has the form where are components of stress, and are the components of the infinitesimal strain tensor. The elasticity tensor has symmetries .

Consider an unbounded anisotropic solid, or matrix, containing a number of arbitrarily oriented anisotropic ellipsoidal inhomogeneities and regarded as the finite cluster model of a particulate composite.

An in-depth tutorial on the thermoelastic constitutive equations for elastic, anisotropic materials is presented. First, basic concepts are introduced that are used to characterize materials, and then notions about how anisotropic material deform are presented.
