It can be concluded that these differences were relatively significant when oil shale was regarded as an isotropic material.
In this section, we will give a natural extension of Hill's class of Hookean compressible materials to transversely isotropic materials at finite strains by the structure tensor method.
For isotropic materials the shear modulus can be obtained by the equation: G = E/2+2v.
The closed-form solutions of Trayer and March (1930) for isotropic material behavior, also given in ASTM D198 (ASTM 2001), and Lekhnitskii (1981) for orthotropic materials were compared to the results of FEA.
Thus, the Young's modulus for a typical isotropic material will range from 2 to 3 times its shear modulus as Poisson's ratio varies from 0 to 0.
If C' = 0, there will be no preferential direction, then the most often used shear velocity corresponds to the case of an isotropic material under unidirectional compression is as shown below [14]:
The core is made from an isotropic material (steel and foam), where L, b, and 2H are the length, the width and thickness of the beam, respectively.
Moreover, if we know that the composite is a two-dimensional isotropic material, then we can define the effective permittivities at points X and Y on the above boundaries, [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII], respectively, using the following equation.
For the heat transfer in isotropic material at axisymmetric conditions, it takes in cylindrical coordinates the following form
But several authors [9, 11] have addressed this issue by stating that bone can be considered as an isotropic material when tested in unique orientation, e.
The program is written in such a way that for given isotropic material parameters, maximum observation time, subscript of the component of the Green's tensor, number of sampling points, and distance between the source and detector, the program will compute the displacement at each sampling time.
