Scientific and Technical Information Program.;]. Defect Green's function (GF) of multiple point-like inhomogeneities in a multilayered solid has been derived within the theory of linear anisotropic elasticity.

When the Fast Hankel Transform filter technique is used to calculate the dyadic multilayered Green's functions, it can be difficult to obtain accurate numerical results because of the branch-cut singularity and the surface wave poles singularity.

The Modified Fast Hankel Transform filter algorithm is proposed to overcome this problem by expressing the Bessel function with a complex argument as. The GFs can be derived using different methods, such as the method of images, the Laplace transform method or the Fourier method of separation of variables.

All these methods produce solutions in different but mathematically equivalent forms. From the computational point of view, the main difference between these methods is the series by: Three-dimensional dynamic Green’s functions for a multilayered transversely isotropic half-space Article in International Journal of Solids and Structures 48(9) May with Reads.

The white areas show the highly directional organization of water density in the first and second structural “shells” arising from the hydrogen bonds – while the orange area shows the depletion region – where no water molecules can reside. The present study investigates the mechanisms of moisture transport in porous materials.

For partially saturated porous materials, moisture transport relies on both the Darcian flow by capillary pressure gradient and the Fickian flow by gas concentration gradient.
