On the contrary, this will not occur in ordinary anisotropic materials or isotropic materials.
Finally, regarding (7), for homogeneous isotropic material two discrete nondimensional elasticity constants are defined explicitly as Poisson's ratio dependant parameters
An ultrasonic immersion technique using custom-built equipment [13] was used to measure the elastic properties of the isotropic material.
Because of the well-known phenomenon of tensile strain localization in polyethylene, bulk samples of oriented material for fracture testing were prepared from isotropic material by using plane strain channel die compression.
When drawn to a draw ratio of 4, the toughness of the pure homopolymer and the blends when tested with the initial notch parallel to the draw direction decreased when compared with the isotropic material.
If the sizes of the domains are very small relative to the crack size, then the overall toughness will be similar to an isotropic material.
For the present case of a transversely isotropic material loaded in two principal directions, Eq 2 can be rewritten in the following form using cylindrical coordinates:
There are almost no areas representative of isotropic material.
The isotropic material is shown as the circle in Fig.
To represent the isotropic material, a piece was machined from the original cylinder, with similar dimensions to the drawn products.
